4y^2 - 7y -15
(y-3)(4y+5)
Answer:
10 pounds of potatoes would cost $15.
Step-by-step explanation:
Set up proportion.
4/6=10/x
simplify 4/6 into 2/3,
2/3=10/x
cross product,
2*x=3*10
2x=30
x=30/2
x=15
Use PEMDAS
first 36-4 = 32
7^2 = 49
(32/16) - 49 is your answer -47
X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x
