Mike started reading a book at 3:35 P. M.
and finished before dinner at 5:30 P. M.
How many minutes did he work?

115 minutes

Step-by-step explanation:

One hour is 60 minutes.

From 5:30 p.m. subtract 3:35 pm, which yields two hours plus five minutes.

Thus, Mike worked (60 + 55) minutes, or 115 minutes.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

the radius is 2 times the diameter.
