Nick needs 65 yards of wire for a project. if the wire is only sold on spools which hold 6 feet of wire, how many spools will he need ?

Step-by-step explanation:

I would first convert the spools into the yard equivalent so 6 ft spools are equal to 2 yard spools now you take 65 divided by 2 which would give you the answer and the answer is 32.5 unless they refuse to sell a partial spool then you would by 33 spools of wire and you would have enough yards of wire with one yard left over

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
