Jensen and Raju had the same amount of money at first. After Jensen spent $64 and Raju spent $148, Jensen had 3 times as much money as Raju. How
much money did each boy have at first?

Step-by-step explanation:

Both of them had $x

Later

Jensen=x-64

Raju=x-148

Jensen=3*Raju

x-64=3(x-148)

x-64=3x-444

3x-x=444-64

2x=380

x=$190

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
