1. Four small pitchers and one large pitcher can hold 10 cups of water. One large
pitcher minus one small pitcher equals 4 cups of water. How many cups of water
can each pitcher hold?

L = 5.2

S = 1.2

Step-by-step explanation:

L + 4S = 10

L + - S = 4

L - L + 4S - - S = 5S = 6

6/5 = S = 1.2

10 - 4(1.2) = 10 - 4.8 = 5.2

L = 5.2  

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
