4. An app developer projects that he will earn
$20.00 for every 8 apps
downloaded. Write
an equation to represent the proportional
relationship between the number of apps
and
the total earnings.

Find the sum of the first 8 terms of the following sequence. round to the nearest hundredth if necessary.

Given that de, df, and ef are midsegments of △abc, and de=3.2 feet, ef=4 feet, and df=2.4 feet, the perimeter of △abc is .

Match each equation with the operation you can use to solve for the variable. 1 subtract 10 2 divide by 10 3add 18 4add 10 5 subtact 18 6multiply by 5. 7multiply by 10. a 5 = 10p b p + 10 = 18 c p + 18 = 5 d 5p = 10
