1)
D=rt
Solve for t
(Hint:divide both sides by r. )

2)

V=lwh
Solve for W

3)
3x+6y=18
Solve for y.

1. t = D/r

2. w = V/lh

3. y = -1/2 + 3

Step-by-step explanation:

1. All you need to do is divide both sides by r to get t by itself

2. All you need to do is divide both sides by lw

3. Since you're solving for y, you need to move 3x by subtracting it from both sides.

3x + 6y = 18

-3x           -3x

6y = -3x + 18

Then you need to get y by itself, so you need to divide both sides by 6, giving you:

y = -1/2x + 3

the answer is c just got it on ed
