Answer:
Rachel's conclusion is valid. The ratios for green beans to total students for the survey and the school form a proportion.
Step-by-step explanation:
Solve using proportions. The format should be "Green beans" on the top, and "Total students" on the bottom.
Simplify the first numerator
Find the <u>common ratio</u>
The common ratio is the number you multiply by to get from the top left to top right. It's the same number the you can multiply the bottom left number by to get the bottom right.
<u>Divide the right side by the left side to find the ratio.</u>
Top: ratio = 240/10 = 24
Bottom: ratio = 600/25 = 24
Since the ratios are <u>the same</u>, they are <u>common</u>.
Therefore the proportion is correct, and Rachel's conclusion is valid.
The value of the 5 is 50 and the value of the 8 is 8 and we know that because of the number of digits after it
X = 4, You subtract the 5x to the other side then divide the 32 by 8 to get 4.

Answer:
Q'(-6, 9), R'(-9, 3), T'(6, -3), W'(6, 12)
Step-by-step explanation:
Each of the individual coordinate values is multiplied by 3.
(x, y) ⇒ (3x, 3y)
__
Q(-2, 3) ⇒ Q'(-6, 9)
R(-3, 1) ⇒ R'(-9, 3)
T(2, -1) ⇒ T'(6, -3)
W(2, 4) ⇒ W'(6, 12)
