Answer:

4r + 4(r + 3) = 68

r = 7 miles per hour

r + 3 = 10 miles per hour

Step-by-step explanation:

a)

4r + 4(r + 3) = 68

Distribute

4r + 4r + 12 = 68

8r + 12 = 68

8r = 56

r = 7 miles per hour

r + 3 = 10 miles per hour

Can someone help please!! i will give brainliest

Answer:

1. $427.50

2. 50 hours

Step-by-step explanation:

1. First, find your salary at minimum hours, which is $360. Then, take your second equation, plug in 45, and solve using PEMDAS. This will give you $427.50

2. To solve this, you'll need to set it up like so:

495 = 13.5 (x - 40) + 360

Your next step will be to distribute the number outside the parentheses. This will give you:

495 = 13.5x - 540 + 360

Simplify, like so:

495 = 13.5x - 180

Solve.

495 = 13.5x - 180

+180             +180

This will give you:

675 = 13.5x

Divide each side.

675 = 13.5x

------    -------

13.5     13.5

  50 = x
