The length of a rectangle is 5.5 inches. The perimeter of the rectangle is greater than 32 inches. Which inequality shows the possible range of widths of the rectangle?

Perimeter 2l + 2w. Using this we can find your inequality equation.

32 = 2(5.5) + 2w

32 = 11 + 2w

21 = 2w

w = 10.5

This means that when the perimeter is 32 in, the width is 10.5 in. We want to know when perimeter is 32 in or greater so we can simply do:

w > 10.5 because anything above 10.5 will increase the perimeter.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
