First, you would need to solve for t using the equation: 3t - 7 = 5t

Move all the numbers with variable on ones side

-7 = 5t - 3t

Combine like factors

-7 = 2t

Solve for t

-7/2 = t

After solving for t, you plug the answer into the equation you want to solve.

6 (-7/2) = -21

6*-7 <u></u>= -42

-42/2 = -21

The answer is -21

ones is before the decimal tenths is one place right of the decimal and hundreths is 2 places to the right of the decimal

so answer would be 3.42

Hence, Height of rectangular prism is 2 feet.

Answer:

for #3, it's to add 12 to both sides, to get:

-9x = 24

for #4, divide both sides by -9, to get:

x=-2.66666666667
