Solve for y. 5y−10=−25 (1 point) Responses 3 3 -3 -3 7 7 -7

Answer 1

To solve for y in the equation 5y - 10 = -25, we need to isolate the variable y.

First, we add 10 to both sides of the equation:
5y - 10 + 10 = -25 + 10
This simplifies to:
5y = -15

Next, we divide both sides of the equation by 5 to solve for y:
5y/5 = -15/5
y = -3

So the solution to the equation is y = -3.

Answer 2

Solve for w. −0.1w+23.2=−0.8 (1 point) Responses -224 -224 -240 -240 240 240 224 224

Answer 3

To solve for w in the equation -0.1w + 23.2 = -0.8, we need to isolate the variable w.

First, subtract 23.2 from both sides of the equation:
-0.1w + 23.2 - 23.2 = -0.8 - 23.2
This simplifies to:
-0.1w = -24

Next, divide both sides of the equation by -0.1 to solve for w:
(-0.1w) / -0.1 = (-24) / -0.1
This simplifies to:
w = 240

So the solution to the equation is w = 240.
