6/10 and 5/10
The common denominator is 10
Answer: see below
<u>Step-by-step explanation:</u>
If the figures are similar, then their corresponding sides are proportional.
ABCD ~ WXYZ

2) y= x times 5
The constant proportion is k=5
3) y=x times 4
The constant proportion is k=4
4)If total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.
Answer:
w = -6
Step-by-step explanation:
Adding 4 to both sides (we do this to get rid of the -4) gives us:
-4 + w + 4 = -10 + 4
w = -6
