The result of multiplying 2y (one-fourth y + three-fourths) is one-half y squared + 6 over 4 y
<h3>Multiplication of numbers</h3>
- 2 y (one-fourth y + three-fourths).
2y(1/4y + 3/4)
= (2y × 1/4y) + (2y × 3/4)
= 2/4y² + 6/4y
= 1/2y² + 3/2y
Given options:
= 9/4y + 11/4
= 1/2y + 6/4
- one-half y squared + 6 over 4 y
= 1/2y² + 6/4y
- 9 over 4 y squared + 11 over 4 y
9/4y² + 11/4y
Therefore, the result of multiplying 2y (one-fourth y + three-fourths) is one-half y squared + 6 over 4 y

Let's call x1: The rate per hour of the number one mechanic. X2: The rate per hour of mechanic number two. The first thing you should do is identify the system of equations that best describes the problem. In this case it is a system of 2 equations with two unknowns which when solved gives a total of x1 = 85 $ / h and x2 = 50 $ / h. Attached solution.
