Chang is driving to Phoenix. Let y represent his distance from Phoenix (in miles). Let x represent the time he has been driving (in hours). Suppose that x and y are related by the equation 225-60x=y. Answer the questions below.

Note that a change can be an increase or a decrease.

For an increase, use a positive number. For a decrease, use a negative number

step-by-step explanation:

idk wbu

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
