What is the value of y when x = 4?
2x - 3y = 20
o a. -9
ob. -4
c. 4
od. 8

2x-3y= -4 because 2x=8 since x=4 so,

8 - 3y = 20
-8. -8

-3y = 12
————
-3
y = -4

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
