Ahmad is riding his bike. the distance he travels varies directly with the number of revolutions (turns) his wheels make. see the graph below.

question 1) how far does he travel per revolution
question 2) what is the slope?

1) Each two revolutions gets us 16 feet, so the answer is

8 feet per revolution

2) What's the slope?

The rate, the distance per revolution, is the slope of distance versus revolutions.

8

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

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
