criag is selling apple cider at a fall festival he prepared 5 gallons of cider which is eqaul to 20. he sold 18 quarts. he wants to know an eqaul amount of cider he will have

Step-by-step explanation:

5 gallons to 20 qts = x gallons to 18 qts

5 x

= cross multiply

20 18

(20)(x) = (5)(18)

20x = 90

x = 90/20

x = 4.5 < 18 qts is equal to 4.5 gallons

20 qts to 5 gallons = 20/5 = 4 qts per gallon <==

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
