Me maria's family drove 140 mi to her grandparents' house and averaged 56 mi/h on the way there. on the return trip, they averaged 50 mi/h . what was the total time maria's family spent driving to and from her grandparents' house? 2.5 h 2.6 h 5.2 h 5.3 h

the answer is 5.3 hours

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

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
