-4(y-2)=12<br> what is the answer
AysviL [449]

Answer:

y=−1

Step-by-step explanation:

Let's solve your equation step-by-step.

−4(y−2)=12

Step 1: Simplify both sides of the equation.

−4(y−2)=12

(−4)(y)+(−4)(−2)=12(Distribute)

−4y+8=12

Step 2: Subtract 8 from both sides.

−4y+8−8=12−8

−4y=4

Step 3: Divide both sides by -4.

−4y

−4

=

Lance used two gallons of paint to pain 785 square feet. How many gallons will he need to purchase to cover 2,500 square feet?
Digiron [165]

Answer:

7 gallon

Step-by-step explanation:

Divide the space that needs paints by how much space has been painted

2500/785 = 3.18

Then double that because it takes 2 gallons to paint every 785 square feet

3.18 x 2 = 6.36

You would need 6.36 gallons of paint, which would round up to 7 because you cannot buy 0.36 of a gallon

How do you do this problem?? I'm very confused
Mamont248 [21]
You have to multiply by the complex conjugate so that you can clear the radical from the denominator. Once you do the multiplication simplify the radical. There's still a common factor in -54, -18, & 75 so divide all those by 3.
