Of the first 5 vehicles in the teachers' parking lot last Tuesday, 2 of them were minivans. Based on this information, if there are 120 vehicles in the parking lot,
how many would you expect to be minivans?

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

d will be the best answer
