-6g+36=12

-6g=12-36

-6g=-24

6g=24

g=24/6

g=4

Answer:

g= - 8

Step-by-step explanation:

Simplifying

-6g + -36 = 12

Reorder the terms:

-36 + -6g = 12

Solving

-36 + -6g = 12

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '36' to each side of the equation.

-36 + 36 + -6g = 12 + 36

Combine like terms: -36 + 36 = 0

0 + -6g = 12 + 36

-6g = 12 + 36

Combine like terms: 12 + 36 = 48

-6g = 48

Divide each side by '-6'.

g = -8

Simplifying

g = -8

Answer:

4/15

Step-by-step explanation:

P(drawing white marble and black marble)

= 6/10 × 4/9 [9 as there is no replacement]

= 4/15

Final answer:

The probability of drawing a white marble first and a black marble second without replacing the first one from a bag of 6 white and 4 black marbles is 12/45, which simplifies to 4/15.

Explanation:

The question is asking to find the probability of drawing a white marble first and then a black marble second from a bag of 6 white marbles and 4 black marbles, without replacing the first marble. To solve this, we calculate the probability of each event separately and then multiply them because the events are independent.

First, the probability of drawing a white marble is calculated by dividing the number of white marbles by the total number of marbles:
P(White first) = 6/10 or 3/5.

Since the first marble is not replaced, there are now only 9 marbles left in the bag, with 5 white and 4 black marbles. Next, the probability of drawing a black marble after drawing a white marble is the number of black marbles over the remaining total number of marbles:
P(Black second | White first) = 4/9.

To find the combined probability of both events happening in sequence, multiply the probabilities:
P(White first and Black second) = P(White first) × P(Black second | White first) = (3/5) × (4/9) = 12/45.

Therefore, the probability of drawing a white marble first followed by a black marble is 12/45, which simplifies to 4/15.

Answer:

y = -2

Step-by-step explanation:

Use the formula for slope: [tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

"m" means slope, and we know it is -1.

Decide which points will be point 1 and point 2

Point 1 (-2, y)    x₁ = -2  y₁ = y

Point 2 (0, -4)   x₂ = 0  y₂ - -4

Substitute the "x" and "y" values into the formula

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m = \frac{-4-y}{0-(-2)}[/tex]                Simplify

[tex]-1 = \frac{-4-y}{2}[/tex]                    Remember m = -1. Get rid of the fraction

Step-by-step explanation:

The first is to identify the operation to be performed, it is a quotient between two potency.

Being two potency of the same base number (10), the property says that the quotient of two potency of the same base subtracts its exponent, and the base remains the same.

The corresponding exponents are 8 and 5.

The subtraction is 8-5 = 3.

The whole number that accompanies the base is divided in a current way, that is 12/4. Therefore, the result is 3.

Answer:

Option C) 2=2 is the last step of Naomi and it is the correct answer

Step-by-step explanation:

Given that Naomi solves a system of equation by Substitution method :

The given system has infinite many solutions

Naomi's last step is 2=2

Then the system of equations has infinite many solutions

Therefore it must be 2=2

Hence option C) 2=2 is the last step and it is the correct answer

The correct last step in a solution with infinitely many solutions is option C, '2 = 2,' which shows that the system of equations is dependent and represents an identity.

When Naomi solves a system of equations using substitution and finds that the system has infinitely many solutions, this means that the two equations are essentially the same line. Therefore, the last step in her solution would demonstrate that the two expressions are identical. Option C, which states 2 = 2, would be the correct answer because it represents an identity, showing that the two sides of the equation are the same no matter what value is chosen for the variables. This is consistent with a situation where the system of equations is dependent, having an infinite number of solutions.

The correct proportion to determine the percentage of red dry erase markers is 'p/100 = 14/56'. By cross-multiplying and simplifying, we find that 25% of the markers are red.

In order to find the percent of dry erase markers that are red, it would be correct to use the proportion 'p/100 = 14/56'. This proportion represents 'p', the percent of red markers out of a total of 100, equal to the actual number of red markers (14) out of the total number of markers (56). Therefore, option A is correct. For example, if you cross-multiply and simplify, you can find the value of 'p' and hence the percentage ratio of red markers. Multiply 14 by 100 to obtain 1400 and then divide 1400 by 56 to obtain 25. Therefore, 25% of the dry erase markers are red.

To represent the actual length of the Mississippi River, which is 2,320 miles, on a map with a scale of 3 cm per 120 miles, the river would be 58 cm long on the map.

The question concerns calculating the scale representation of the actual length of the Mississippi River on a map. According to the given scale, 3 centimeters on the map represents 120 miles in reality. The actual length of the Mississippi River is 2,320 miles. To find the length of the Mississippi River on the map, we use the scale ratio to set up a proportion.

First, we calculate the scale ratio which is 3 cm to 120 miles. This means 1 cm represents 40 miles (120 miles ÷ 3 cm). To find how many centimeters represent 2,320 miles, we divide the actual miles by the miles each centimeter represents. Therefore, 2,320 miles ÷ 40 miles/cm equals 58 cm. Thus, the Mississippi River would be represented as 58 cm long on Kim's map.

Final answer:

When dividing 0.7 by 0.1995, it is crucial to perform the calculation accurately and round it according to the significant figures of the original numbers. Calculators will provide an exact answer, but understanding significant figures is necessary for a correctly rounded result.

Explanation:

Dividing Decimals

When we divide 0.7 by 0.1995, we have to handle decimals properly. It's similar to how a calculator operates but with an understanding of significant figures. The division of decimals can be tricky because calculators give an exact numerical value, which may not respect the precision of the input numbers.

For instance, if we divide 12.2 by 1.7 using a calculator, we get many decimal places. But based on the initial data's significant figures, we must round our answer appropriately. Similarly, if we divide 1.9436 by various powers of 10, we get:

1.9436 ÷ 100 = 0.019436

1.9436 ÷ 1000 = 0.0019436

When dividing by powers of 10, we move the decimal point to the left for each power. In more complex divisions or when your calculator presents more decimals than necessary, it is important to round the answer to the correct number of significant figures.

Final answer:

The coordinates of vertex W of parallelogram WXYZ, given vertices X(-2,-3), Y(0, 5), and Z(7, 7), are W(9, 15). This is found by calculating vector ZW as equal to vector XY and adding ZW to the coordinates of Z.

Explanation:

The coordinates of vertex W of parallelogram WXYZ can be found by using the properties of parallelograms. In a parallelogram, opposite sides are equal in length and parallel. Given vertices X(-2,-3), Y(0, 5), and Z(7, 7), we can first find the vector representation from X to Y and from Y to Z:

To find the vector from Z to W, which we'll call ZW, we use the fact that ZW must be parallel and equal in length to vector XY. Therefore:

Now we add vector ZW to the coordinates of Z to find W:

Thus, the coordinates of vertex W are (9, 15).

The trip lasts for [tex]6\frac{1}{4}\ hours[/tex]

Solution:

Mr Patel is planning to drive 325 miles

Average speed is 65 mph

He will stop one hour for lunch and take a 15 min rest break

Let us first find the time taken

[tex]Time = \frac{distance}{speed}[/tex]

[tex]Time = \frac{325}{65}\\\\Time = 5[/tex]

Thus he covers 325 miles in 5 hours

Also, given that, he will stop one hour for lunch and take a 15 min rest break

Therefore, total time taken for trip is:

Total time = 5 hours + 1 hour + 15 minutes

Total time = 6 hours 15 minutes

We know that,

1 hour = 60 minutes

Therefore,

[tex]6\ hours\ 15\ minutes\ = 6 + \frac{15}{60}\ hours = 6 + \frac{1}{4} = 6\frac{1}{4}\ hours[/tex]

Thus the trip lasts for [tex]6\frac{1}{4}\ hours[/tex]

Mr. Patel's trip will last a total of 6.25 hours, including his driving time, lunch break, and rest break. The calculation was done using the formula Time = Distance / Speed, and factoring in the break times.

First, we need to calculate how many hours Mr. Patel will spend driving. To do this, we use the formula Distance = Speed * Time. We rework this formula to find time, giving us Time = Distance / Speed. So, Mr. Patel’s total driving time is 325 miles divided by 65 mph (miles per hour), which equals 5 hours.

The next task is to factor in Mr. Patel’s lunch and rest breaks. He takes one hour for lunch and 15 minutes for a rest break. Note that 15 minutes is 0.25 of an hour. Add these two periods to our initial 5 hours of driving time, and we get a total of 6.25 hours. So, Mr. Patel's trip will last 6.25 hours, which corresponds to answer choice D).

To find the equation of a line parallel to a given line and passing through a given point, use the point-slope form of a line.

To find the equation of a line parallel to the given line, we need to remember that parallel lines have the same slope. The given line has a slope of 1/5. So, the parallel line will also have a slope of 1/5. We can use the point-slope form of a line to find the equation. The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Plugging in the values, we get:

y - 2 = 1/5(x + 2)

To simplify the equation, we can multiply through by 5 to get rid of the fraction:

5y - 10 = x + 2

Finally, we can rearrange the equation to the standard form:

To find the percent of discount, subtract the sale price from the original price, divide by the original price, and multiply by 100. The percent of discount is 30%.

Explanation:

To find the percent of discount, we need to calculate the difference between the original price and the sale price, and then divide it by the original price and multiply by 100.

Original price - Sale price = $129 - $90.30 = $38.70

Percent of discount = ($38.70 / $129) * 100 = 30%

Therefore, the percent of discount is 30%, which is option B.

Answer:

It will take 1/2 of a year or 6 months for these trees to be the same height.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Type A is 2 feet tall and grows at a rate of 25 inches per year.

Type B is 10 feet tall and grows at a rate of 9 inches per year.

2. Algebraically determine exactly how many years it will take for these trees to be the same height.

x = Number of years

Type A = 2 + 25x

Type B = 10 + 9x

Let's solve for x, using the following equation:

Type A =  Type B

2 + 25x = 10 + 9x

25x - 9x = 10 - 2

16x = 8

x = 8/16 = 1/2

It will take 1/2 of a year or 6 months for these trees to be the same height.

Let's prove it, this way:

2 + 25x = 10 + 9x

2 + 25 (1/2) = 10 + 9 (1/2)

2 + 25/2 = 10 + 9/2

Step-by-step explanation:

3(x + 1) = 2(x - 1)​

Distribute on both sides.

3x + 3 = 2x - 2

Subtract 2x from both sides.

x + 3 = -2

Subtract 3 from both sides.

x = -5

Answer:

The answer you are looking for is x = -5.

Step-by-step explanation:

First, start by distributing the 3 and 2.  This will remove the parentheses.  The way you do this is by multiplying each number or variable inside the parentheses by the number outside the parentheses.

3x + 3 = 2x - 2

Next, get the variable to one side.  One way to accomplish this is by subtracting 2x from each side.

x + 3 = -2

Lastly, move the numbers to one side.  Do this by subtracting 3 from both sides.

x = -5

There you go.  Your answer is now in the simplest form.  Confirm the answer is as simple as plugging in -5 for x in the original equation.

In order to increase the area of a rectangular garden that measures 12 feet by 14 feet by 50% Jake must increase each dimension by equal lengths, x:
