Answer:
y= 4
Step-by-step explanation:
-32= 4(y -5) -7y
Expand:
-32= 4y -20 -7y
Simplify:
-32= -3y -20
+20 on both sides:
20 -32= -3y
Simplify:
-12= -3y
Divide both sides by -3:
y= -12 ÷(-3)
y= 4
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
