The height of an ice sculpture is 5 feet before it starts to melt. As the ice sculpture melts, its height decreases by 0.5 foot per hour. Write an equation to represent the height of the ice sculpture (y), in feet, based on the amount of time (x), in hours, since it started to melt?

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

the answer is c 150
