Which expression has a value that is equivalent to the given expression when n = 8? 2n + 10 a. 3n b. 2(n + 5) c. n² + 5 d. 10n + 2

2n + 10 = 2(8) + 10 = 16 + 10 = 26

same as

2(n + 5) = 2(8 + 5) = 2(13) = 26

Answer

B. 2(n + 5)

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
