Step-by-step explanation:
21 2/2=1
42 4/2=2
63 6/2=3
84 8/2=4
Answer:
5. x=14
6 x=5
Step-by-step explanation:
31+9x+23=180
step 1 combine like terms
54+9x=180
step 2 subtract each side by 54
9x=126
step 4 divide each side by 9
x=14
21x-9=90+27
step 1 combine like terms
21x-9=117
step 2 add 9 to each side
21x=126
step 3 divide each side by 21
x=5
Well, we want to find how much it would cost for 1 gallon, the easiest way to do that is subtract 21 from 18.
21 - 18 = 3
So, it's 3 dollars per gallon. Now that we know that we multiply it by 8 to find how much it would cost.
8 x 3 = 24
Eight gallons of gas would cost 24$ :D
