I need to find what the variable is in this equation -7+m=-9

Answer:

x = -1 or 5

Step-by-step explanation:

From the expression (x +1) (x - 5)

We’re to solve for x.

Therefore,

x + 1 = 0

Subtract one from both sides

x + 1 - 1 = 0 - 1

x = -1

x - 5 = 0

Add five to both sides

x - 5 + 5 = 0 + 5

x = 5

Answer:

Length = 30√2 yards.

Step-by-step explanation:

There is a plot of land of square shape that has 30 yards on each side. Jules owns this plot. He plans to divide the land in half by building a fence along the diagonal of the plot.

We have to calculate the length of the fence.

Now, the length of the diagonal will be the length of the fence.

So, the length = [tex]\sqrt{30^{2} + 30^{2}} = 30\sqrt{2}[/tex] yards. (Answer)

Step-by-step explanation:

infinity numbers above 12

The inequality x > 12 has infinitely many solutions as it represents all numbers greater than 12 without any upper limit.

The inequality x > 12 actually has infinitely many solutions, since any number greater than 12 satisfies the inequality condition.

In mathematics, inequalities that do not contain restrictions other than the comparative operator (in this case, '>') have a set of solutions that can be represented on a number line extending infinitely in one direction.

For example, if x > 12, then numbers such as 13, 14.5, 100, and 1234 are all solutions.

This can be visualized on a graph where x > 12 would be shown as an open interval starting from 12 and extending to the right toward infinity.

To find out how many children like each drink in a year group of 60 pupils, calculate each fraction of the total. 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.

Explanation:

In a year group of 60 pupils, to find out how many children like each drink, you need to calculate the fractions of the total number of pupils.

Therefore, 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.

Final answer:

45 children like Coke, 12 children like Sprite, and 18 children like Tango.

Explanation:

To find out how many children like each drink, we can use the given fractions and the total number of children in the year group.

Let's calculate the number of children who like Coke:

Total children in the year group = 60

Fraction who like Coke = 3/4

Number of children who like Coke = (3/4) x 60 = 45

Similarly, we can calculate the number of children who like Sprite and Tango:

Fraction who like Sprite = 1/5

Number of children who like Sprite = (1/5) x 60 = 12

Fraction who like Tango = 3/10

Number of children who like Tango = (3/10) x 60 = 18

Therefore, 45 children like Coke, 12 children like Sprite, and 18 children like Tango.

Measure of angle x = 74

Measure of angle y = 90

Step-by-step explanation:

The required measure of angle x in the triangle inscribed in the circle is 74°.

Following the given, there is a property of a circle that states that, the angle subtended through the endpoints of the longest chore of the circle(i.e. diameter) on the circumference of a circle is always 90°.
So, y = 90°
Now,
The measure of angle x is given as:
[tex]x + 90 + (180-148)/2 = 180[/tex]
x = 74

Thus, the requried measure of angle x in the triangle inscribed in the circle is 74°.

Answer:

x = (-7)/5

Step-by-step explanation:

Solve for x:

3 (x - 6) - 8 x = 5 (2 x + 1) - 2

3 (x - 6) = 3 x - 18:

3 x - 18 - 8 x = 5 (2 x + 1) - 2

Grouping like terms, 3 x - 8 x - 18 = (3 x - 8 x) - 18:

(3 x - 8 x) - 18 = 5 (2 x + 1) - 2

3 x - 8 x = -5 x:

-5 x - 18 = 5 (2 x + 1) - 2

5 (2 x + 1) = 10 x + 5:

-5 x - 18 = 10 x + 5 - 2

Add like terms. 5 - 2 = 3:

-5 x - 18 = 10 x + 3

Subtract 10 x from both sides:

(-5 x - 10 x) - 18 = (10 x - 10 x) + 3

-5 x - 10 x = -15 x:

-15 x - 18 = (10 x - 10 x) + 3

10 x - 10 x = 0:

-15 x - 18 = 3

Add 18 to both sides:

(18 - 18) - 15 x = 18 + 3

18 - 18 = 0:

-15 x = 3 + 18

3 + 18 = 21:

-15 x = 21

Divide both sides of -15 x = 21 by -15:

(-15 x)/(-15) = 21/(-15)

(-15)/(-15) = 1:

x = 21/(-15)

The gcd of 21 and -15 is 3, so 21/(-15) = (3×7)/(3 (-5)) = 3/3×7/(-5) = 7/(-5):

x = 7/(-5)

Multiply numerator and denominator of 7/(-5) by -1:

The value of b is -3

Explanation:

The function is [tex]f(x)=\frac{1}{4} x^{2} +bx+10[/tex] and [tex]x=6[/tex]

The function is of the form [tex]y=a x^{2}+bx+c[/tex]

where [tex]a=\frac{1}{4}[/tex], [tex]b=b[/tex] and [tex]c=10[/tex]

Using the axis of symmetry formula, we can determine the value of b.

Thus, the axis of symmetry formula is given by,

[tex]x=\frac{-b}{2a}[/tex]

Substituting the values, we have,

[tex]6=-\frac{b}{2(\frac{1}{4}) }[/tex]

Multiplying the denominator, we get,

[tex]6=-\frac{b}{\frac{1}{2} }[/tex]

Dividing, we get,

[tex]6=-2b[/tex]

Dividing both sides by -2, we get,

[tex]-3=b[/tex]

Hence, the value of b is -3.

The price per square foot is 0.55$

Step-by-step explanation:

We can solve this problem by applying the rule of three.

In fact, we know that:

- The price per 1 gallon is $55

- The area covered by 1 gallon is [tex]100 ft^2[/tex]

So this means that the price per [tex]100 ft^2[/tex] (1 gallon) is $55.

Here we want to find the price per square foot, so we can write:

[tex]\frac{x}{1}=\frac{55}{100}[/tex]

And solving for x, the price per square foot, we find:

[tex]x=\frac{55}{100}=0.55[/tex]

So, the price per square foot is 0.55$.

The price per square foot for paint that costs $55 per gallon and covers 100 square feet is $0.55.

Explanation:

To calculate the price per square foot for paint that costs $55 per gallon and covers 100 square feet, we need to divide the total cost by the total coverage area. Here is the step-by-step calculation:

Determine the total cost of one gallon of paint: $55

Determine the total coverage of one gallon of paint: 100 square feet

Calculate the price per square foot: $55 ÷ 100 sqft = $0.55 per sqft

Therefore, the price per sqft of paint is $0.55.

Step-by-step explanation:

The probability that a point chosen inside a circle will also be inside a square is π/4.

The probability that a point chosen inside a circle will also be inside a square can be determined by comparing the areas of the circle and the square. Let's assume that the circle has a radius of r and the square has sides of length 2r. The area of the circle is πr2 and the area of the square is (2r)2 = 4r2. Therefore, the probability of the point being inside the square is given by the ratio of the area of the circle to the area of the square: P = (πr2) / (4r2) = π/4.

Final answer:

The algebraic equation 7(x-10)-2(x+5)=4x-7+6x-3 simplifies through distribution, combining like terms, and isolating x, resulting in the solution x = -14.

Explanation:

The student's question involves solving the algebraic equation 7(x-10)-2(x+5)=4x-7+6x-3. To solve this equation, we will simplify and solve for x, demonstrating the process step-by-step.

Step 1: Distribute and Simplify

First, distribute the numbers outside the parentheses:
7(x-10) becomes 7x - 70 and
-2(x+5) becomes -2x - 10.

The equation now looks like 7x - 70 - 2x - 10 = 4x - 7 + 6x - 3.

Step 2: Combine Like Terms

On the left side of the equation, combine 7x and -2x to get 5x. Also, combine -70 and -10 to get -80.
On the right side, combine 4x and 6x to get 10x, and -7 with -3 to get -10.

Step 3: Further Simplification and Solving for x

Now, the equation is 5x - 80 = 10x - 10. Subtract 5x from both sides to get -80 = 5x - 10. Adding 80 to both sides gives us 0 = 5x + 70. Subtract 70 to get 5x = -70. Finally, divide by 5 to find that x = -14.

In conclusion, through the steps of distribution, combining like terms, and isolating x, we find the solution to the original algebra problem to be x = -14.

Answer:

117 and 123.

Step-by-step explanation:

If the 2 numbers are x and y we have the system of equations:

x - y = 6

xy = 14391

From the first equation y = X - 6  so substituting:

x(x - 6) = 14391

x^2 - 6x= 14391

x^2 - 6x - 14391 = 0

The prime factors of -13491  are -3*3*3*13*41

Now  3*3*13 = 117 and -3 * 41 = -123,

so the factors are:

(x - 123)(x + 117) = 0.

x = 123, -117.

As x is a whole number we take the positive value 123.

So x = 123  and y = 123 - 6 = 117.
