-2(4 - 3x) + (5x - 2)

Answer:

Option A

Step-by-step explanation:

It is given that Marta sold [tex]$ x $[/tex] oranges on Thursday.

She has sold twice as many as on Friday. Therefore, she must have sold [tex]$ 2x$[/tex] oranges on Friday.

And the total amounts to 108.

That is, [tex]$ x + 2x = 108 $[/tex]

Hence, the table which has the total on the top and the entities on the bottom line would be the answer which is Option A.

Answer:

A

Step-by-step explanation:

Thursday is x because she sold x oranges. Friday is 2x because she sold double the amount she sold on Thursday. Then we add them together to make 108.

A. A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R.

Step-by-step explanation:

Since both the trapezoids, trapezoid JKLM and PQRS are congruent, we can do any transformation, may be rotation, reflection and translation.

A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R is the true statement others are incorrect statements.

When the Preimage is rotated 90° counterclockwise rotation, then its coordinates (x,y) changed into (-y,x)  

Answer:

3 inches

It will fit in the paper.

Step-by-step explanation:

In the scale drawing the 2 feet original length is converted to 1 inch drawing length as Kelly constructs a scale model of the rock garden using the scale 1 inch  : 2 feet.

Now the proportion is 1 inch : (2 × 12) inches = 1 : 24 {Since 1 foot is equivalent to 12 inches}

Now, maintaining that scale ratio the 6 feet original length of the garden will be converted to [tex]\frac{1}{24} \times (6 \times 12) = 3[/tex] inches in the drawing.

It is also given that the width of the garden in the scale model is 5 inches and the scale is still 1 inch : 2 feet.

Therefore, the dimensions of the garden in the model is 3 inches by 5 inches and this will fit on a piece of paper that is 8.5 inches by 7 inches. (Answer)

The solution for equation is x = -6

Solution:

Given equation is:

[tex]5(x-2) + (-9) = -7(1-x)[/tex]

We have to solve the equation

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

Therefore, solve for brackets in given equation

[tex]5(x-2) + (-9) = -7(1-x)\\\\5x - 10 -9 = -7 + 7x[/tex]

Solve for terms in left hand side of equation

[tex]5x - 19 = -7+7x[/tex]

Move the variables to one side and constants to other side

[tex]7x -5x = -19+7\\\\2x = -12\\\\Divide\ both\ sides\ by\ 2\\\\x = -6[/tex]

Thus the solution for equation is x = -6

Answer:

2 thirds of the trails are longer than 5 Km

Step-by-step explanation:

A line plot that forms a straight line indicates a direct relationship between the two variables plotted. A graph that shows less deviation from the line of best fit is a good candidate for linear regression. Line graphs are typically used to show trends over time.

When considering a line plot or any graphical representation of data such as scatter plots or line graphs, the main goal is to uncover the underlying pattern or relationship presented. If the data, when graphed, forms a straight line, it suggests a direct relationship between the variables involved. This implies that as one variable increases, the other variable either increases or decreases by a consistent rate. For instance, if one plot shows a line from (0,8) to (3,2), there's a decrease as the first variable increases. Conversely, a line from (0,2) to (3,2) or from (0,3) to (3,3) suggests no change, indicating a directly horizontal line and therefore no relationship. When determining good candidates for linear regression, a scattering of points closely aligned in a straight line pattern, with little deviation from the line of best fit, is indicative of such. Linear regression is more accurate when the variance around the line of best fit is minimal, as seen in the second graph described. Line graphs specifically are useful for showing data trends over time, where the x-axis typically represents time and the y-axis represents another variable.

Answer:

The total cost of the car including the down payment  = $12,500

Step-by-step explanation:

The Original price of the car  = $9800

The amount paid for down payment  = $500

Also, the monthly payment  amount  = $250

Now, the number of months, the amount is paid  = 48 months

So, the TOTAL amount paid in 48  months

= 48 x ( Amount paid each month)   = 48 x ( $250)

= $12,000

So, the TOTAL PRICE of CAR paid  = Total amount paid in 48 months  + The amount paid for down payment

= $12,000 +  $500

= $12,500

Hence, the total cost of the car including the down payment  = $12,500

Reflection through y-axis.

Answer:wait

Step-by-step explanation:

x ≤ 12

Solution:

Let us take the number be x.

A number : x

A number divided by three : [tex]$\frac{x}{3}[/tex]

A number divided by three less two : [tex]$\frac{x}{3}-2[/tex]

A number divided by three less two is at most two : [tex]$\frac{x}{3}-2\leq 2[/tex]

Now, simplify the inequality,

[tex]$\Rightarrow\frac{x}{3}-2\leq 2[/tex]

Add 2 on both sides of the inequality,

[tex]$\Rightarrow\frac{x}{3}-2+2\leq 2+2[/tex]

[tex]$\Rightarrow\frac{x}{3}\leq 4[/tex]

Multiply by 3 on both sides of the equation,

[tex]$\Rightarrow\frac{x}{3}\times3\leq 4\times3[/tex]

[tex]$\Rightarrow x\leq 12[/tex]

Hence x ≤ 12.

Final answer:

The question requires setting up an inequality to express the condition 'a number divided by three less two is at most two.' The solution of the inequality reveals that the number in question is any number less than or equal to 12.

Explanation:

The student's question involves a number theoretical concept that requires setting up and solving an inequality. To understand the requirement of 'at most two' when a number is divided by three and reduced by two, we would establish an inequality as X / (3-2) ≤ 2, where X is the unknown number. This inequality represents the condition mentioned in the question, which restricts the value of X to a certain range after the operations are performed.

When working through the inequality, we aim to isolate X to determine the possible values it can hold. Here, we would start by adding two to both sides of the inequality to remove the subtraction, leading to X / 3 ≤ 4. Multiplying both sides by 3 gives us X ≤ 12. This tells us that the number in question is any number that is less than or equal to 12.

Understanding mathematical operations and the interpretation of numerals in context is necessary to solve such problems. Specifically, discerning the difference between an 'at least' and 'exactly' reading of numerals impacts the formation and solution of such inequalities.

Answer: 8 squared equals 8 plus 56

Step-by-step explanation:

What you would do is find a number squared that is greater than 56. I used 8 because 8 squared is 64. So i squared that and got 64, I then subtracted 8 from 64 because you would need to use the same x value in the equation and that lead me t getting 56. All in all x=8.

Since this statement is true, x=-14 is a solution.

The number -14 is a solution to the inequality X > -17 in mathematics as it falls within the range of numbers greater than -17.

In the realm of mathematics, inequalities define a range of values that can be a solution. In this case, the inequality is X > -17. This means any number greater than -17 is a solution to the inequality. If we consider -14, it falls within this range because -14 is greater than -17. Therefore, yes, -14 is a solution to the given inequality.

Roxy has 7 necklaces.

Step-by-step explanation:

35 = n + 4n

35 = 5n

5  =   5

n = 7

The problem is a simple algebra problem related to ratios. By setting up an equation according to the given information, we find that Roxy has 7 necklaces.

This is a math problem concerning ratios and simple algebra. Let's denote the number of necklaces that Roxy has as R. Then, Kelly has 4 times more rings, which is 4R. Together they have 35. So, the equation can be set up as:

R + 4R = 35

Combine like terms, you get:

5R = 35

Then, you can solve for R by dividing both sides by 5:

R = 35/5 = 7

So, Roxy has 7 necklaces.

The x intercept is [tex](\frac{-2}{5}, 0)[/tex]

The y intercept is [tex](0, \frac{-2}{3})[/tex]

Solution:

Given equation is:

10x + 6y = -4

The x intercept is the point where the line crosses the x axis

The y intercept is the point where the line crosses the y axis

Find x intercept:

Substitute y = 0 in given equation

10x + 6(0) = -4

10x = -4

[tex]x = \frac{-4}{10}\\\\x = \frac{-2}{5}[/tex]

Thus the x intercept is [tex](\frac{-2}{5}, 0)[/tex]

Find y intercept:

Substitute x = 0 in given equation

10(0) + 6y = -4

[tex]6y = -4\\\\y = \frac{-4}{6}\\\\y = \frac{-2}{3}[/tex]

Thus the y intercept is [tex](0, \frac{-2}{3})[/tex]
