An 5 in. by 7 in. photo is reduced so that the width (the shorter dimension) is 4 in. What is the length of the reduced photo?

What is the length of the reduced photos
4in
3.75 in
5.25 in
5.60 in

5.60 in

Step-by-step explanation:

4 / 5 = x / 7 Multiply both sides by 7

28/5 = x Divide 28 and 5

5.6 = x

So the answer would be 5.60 inches.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
