Rodrigo practiced playing guitar 15 1/3 hours over the past 3 weeks. he practiced for 6 1/4 hours during the first week and 4 2/3 during the second week. how much time did rodrigo spend practicing during the 3rd week? use the numbers and symbols to write an equation that represents the problem. then solve the equation. symbols may be used more than once.

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
