what is the solution to the proportion? 8/x = 5/10

a. 6.25 b. 80 c. 13 d. 16

I think it would be C but that’s just my opinion

D. 16

Step-by-step explanation:

8/x=5/10.

if you cross multiply, it gives you 5x=8*10 which equals to 5x=80.

Then, you divide 80 by 5 to leave the x by itself. 80 divided by 5 is 16.

Another way is 5/10 equals 1/2 so you find the double of 8 which is 16. 8/16=1/2 -> 1/2=1/2 so that means that 8/16 can equal 5/10

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).

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
