Will brought 3 college textbooks one cost 32, one cost 45, and one cost 39 what is the average price of his books

c) yes, because of asa or aas

47 - 90 = 43

43 - 180 = x

x = 137

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
