X= -2 Step 1: Simplify both sides of the equation. 3-x=5 Simplify: (Show steps) -x+3=5 Step 2: Subtract 3 from both sides. -x+3-3=5-3 -x=2 Step 3: Divide both sides by -1. -x/-1= 2/-1 X= -2

Solve 9x−y=45 for y.
Taya2010 [7]

So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

-y=-9x+45

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:

y=9x-45

I NEED PLEASE IT WOULD REALLY HELP ME ALOT !!<br><br><br> NO LINK OR ZOOMS
Karolina [17]

Answer:

C

Step-by-step explanation:

Don't worry about the volume to start with. Just look at the area of the top or bottom.

The hole has a 4 inch diameter

d = 4

r = d/2

r = 2

Area = pi r^2

Area = pi * 2^2

Area = 4 pi

Now find the area of the top (or bottom) if the circle was not there.

L = 8

W = 6

Area = L * W

Area = 8 * 6

Area = 48

Now take away the area of the circle.

Area Top = 48 - 4 * pi

Area Top = 48 - 12.56

Area Top = 35.44

Finally, Find the volume

Volume = area of the top * height

Volume = 35.44 * 15

Volume = 531.6
