ABC = DEF
AB = DE , AC = DF & BC = EF ( means similar )
EF = 4times BC
So, the triangle DEF is 4times the triangle ABC
EF = 24 and BC = 6
So, AB = DE/4 = 32/4 = 8
3h
The set cost is 25, because c=25 when h=0. So, this leaves 3h as the hourly rate.
Step-by-step explanation:
5 (18 - y) when y=6
5 (18 - 6)
5 × 18 - 5× 6
90 - 30
60
