Question

Jamie and Raul both work at the Pizza House. Together, they work a total of 15 hours per week. Raul works 3 more than twice the hours as Jamie. How many hours does Jamie work per week?

Enter your answer in the box.

Answer 1

Explanation:

List the facts phrase by phrase.

Total = 15 hours

Let Raul's hours = x

Let Jamie's hours = y

Total = x + y = 15

x = 3 + 2y

From total, find x

x+ y = 15 Subtract y from both sides.

x = 15 - y Put the value for x in x = 3+ 2y

3 + 2y = 15 - y Subtract 3 from both sides

2y = 15 - 3-y Combine

2y = 12 - y Add y to both sides.

2y + y = 12 Combine

3y = 12

y = 12 / 3

y = 4

Jamie worked 4 hours

Raul worked 11
