This one is deceiving my simple. Start with the ratio 2/3. To find more ratios that are proportionate, simply multiply the numerator and denominator by the same number. Let's go with 2. So, 2*2/2*3 (which is 4/6) should be equal to 2/3. If you plug both into a calculator, you will see that they both equal 0.667, and are therefore proportionate.
Here are some more examples:
2/3, 4/6, 6/9, 8/12, 10/15
Answer:
The answer is B: Store Z has the best sale price of $28.
Step-by-step explanation:
Store X: $29.75
Store Y: $30
Store Z: $28
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:
1) 16
2a) 100 -a -2b
2bi) (100 -a -2b)/4
2bii) 11
Step-by-step explanation:
1. Put the numbers where the corresponding variables are and do the arithmetic.
(2(1) +3(-2))^2 = (2 -6)^2 = (-4)^2 = 16

2. The pieces cut from the wire have the lengths a, b, b. The sum of those lengths is a+b+b = a+2b.
2a. The remaining length is what is left when the total of cut pieces is subtracted from the original amount:
100 -(a+2b) = 100 -a -2b
2bi. The perimeter of the square is the amount in part (2a). A square has 4 sides of the same length, so each side has a length that is 1/4 of the perimeter. The side length is ...
(100 -a -2b)/4 . . . . length of one side of the square
2bii. Fill in the given values for "a" and "b" and do the arithmetic.
(100 -24 -2(16))/4 = (76 -32)/4 = 44/4 = 11 . . . one side of the square
