Question

Write and solve an equation of the form "px + q = r" to find the number of hours Geoff worked his first week. If Geoff worked 15 hours in his first week, what is the correct equation?

A) 2x + 13 = 15
B) 2x + 15 = 13
C) 2x + 13 = 2
D) 2x + 15 = 2

Answer 1

The correct equation to find the number of hours Geoff worked his first week is A) 2x + 13 = 15. Geoff worked 1 hour in his first week.

Step-by-step explanation:

The correct equation to find the number of hours Geoff worked his first week is A) 2x + 13 = 15.

1. Let x be the number of hours Geoff worked his first week.
2. Set up the equation: 2x + 13 = 15.
3. Solve the equation: 2x = 15 - 13 = 2. Divide both sides by 2 to solve for x: x = 1.

Therefore, Geoff worked 1 hour in his first week.
