Mila [183]

Answer:

d) 87

Step-by-step explanation:

to solve this lets set up the equation

$\frac{85+70+98+x}{4} =85\\\frac{253+x}{4} =85$

then we multiply 4 on both sides

253+x=340

and subtract 253 on both sides

x=87

to double check take the averages

(87+85+70+98)/4=85

A rectangle has a perimeter of 16p centimeters. It has a width of 2p centimeters. Find the length of the rectangle in terms of p

DIA [1.3K]

If the width is 2p then the width of both sides is 4p. Subtract that from the total perimeter and you get 16p-4p= 12p. Divide that by two because there are 2 side lengths. So, one side length is 6p.
