Answer:

Step-by-step explanation:

Givens

4 sides = 4*p

3 sides = 3(4p) = 12p

Other sides

Total length = 138 inches

Equation

4p + 12p + 10 + 12 + 4 = 138

Solution

Collect like terms

16p + 26 = 138

Subtract 26 from both sides

16p + 26 - 26 = 138 - 26

16p = 112

Divide by 16

16p/16 = 112/16

p = 7

Longest Side (Answer)

7 * 4 = 28 inches

Elizabeth made an English muffin pizza using 1/4 cup of cheese and 3/8 cup of sausage. How many cups of toppings did she use?

Sonbull [250]

Answer: The answer is $\dfrac{5}{8}~\textup{cups}.$

Step-by-step explanation: Given that Elizabeth made an English muffin pizza by adding the following quantities of cheese and sausage..

Cups of cheese used by Elizabeth is given by

$C_c=\dfrac{1}{4}~\textup{cups}.$

And cups of sausage used by Elizabeth is given by

$C_s=\dfrac{3}{8}~\textup{cups}.$

Therefore, total number of cups of toppings used by Elizabeth is

$C=C_c+C_s=\dfrac{1}{4}+\dfrac{3}{8}=\dfrac{5}{8}~\textup{cups}.$

Thus, the number cups of toppings used is $\dfrac{5}{8}~\textup{cups}.$
