Answer:

85 = 5x + 20 is the inequality.

Step-by-step explanation:

Why is it right? Because I said so.

Just kidding. Here:

The cost of the games, 5, is multiplied by x, which is the amount of games that Angel will buy. To solve:

Subtract 20 from both sides:

65 = 5x

Divide 65 by 5.

The answer of the question is: Angel can buy 13 games. (Angel! That's a waste of 65 bucks!)

Answer:

Part a) AB=15\ cm

Part b) AB=11.1\ cm

Part c) AB=3/5\ cm

Part d) AB=3s\ cm

Step-by-step explanation:

see the attached figure to better understand the question

we know that

To find the length of the image after a dilation, multiply the length of the pre-image by the scale factor

Part a) we have

The scale factor is 5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(5)=15\ cm

Part b) we have

The scale factor is 3.7

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(3.7)=11.1\ cm

Part c) we have

The scale factor is 1/5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(1/5)=3/5\ cm

Part d) we have

The scale factor is s

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(s)=3s\ cm

Solve four square root of six plus eight square root of four and explain whether the answer is rational or irrational.
Inga [223]

Answer:

4\sqrt{6}+16

Step-by-step explanation:

Given the expression: 4\sqrt{6}+8\sqrt{4}

\sqrt{4}=2\\$Therefore, \\4\sqrt{6}+8\sqrt{4}  =4\sqrt{6}+8*2\\  =16+4\sqrt{6}

We can re-write the answer as:

4\sqrt{6}+16

The answer is irrational because the sum of a rational number and irrational number is an irrational number.

<u>The correct option is B.</u>

tell whether this has one solution, infinitely many solutions, or no solution. Explain your reasoning. y=2x+7, y=3x-1
hammer [34]

Answer:

One solution

Step-by-step explanation:

They have isolated y for you in both equations so you can plug either one into the other.

y = 3x - 1

2x + 7 = 3x - 1

isolate the x

7 = x - 1

x = 8

Go back to the original and plug 8 into x to get y.

y = 2 (8) + 7

y = 16 + 7

y = 23

This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
