Students in 7th grade took a standardized math test that
they also had taken in 5th grade. The results are shown
on the dot plot, with the most recent data shown first.
Find and compare the means to the nearest tenth.

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

a negative exponent is translated as follows:

so, we have

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
