Jamal works as an electrician’s apprentice. he rewired 4 electrical outlets in 1 1/2 hours. if he works at the same pace for 7.5 hours, how many outlets will he rewire?
5 outlets
13 outlets
20 outlets
30 outlets

This can be solve by first solving the proportionality constant

Number electic outlets rewired is directly proportional to time spent

4 = (1 ½)a

Let be the proportionality constant

A = 8/3

O = (8/3)(7.5)

o = 20 outlets will jamal rewired if he works for 7.5 hrs 

o = 20 outlets will jamal rewired if he works for 7.5 hrs

Step-by-step explanation:

3x - 2y = –9

3x−2y+2y=−9+2y

3x=2y−9/3x^3

=2y−9/3

x=2/3y−3

4x + 3y = 22

4x+3y+−3y=22+−3y

4x=−3y+22

4x4

=−3y+22/4

x=−3/4y+11/2
