Step-by-step explanation:
6z + 8 = 200
subtract 8 from each sides
6z + 8 - 8 = 200 - 8
simplify --> 6z = 192
6z/6 = 192/6
z = 32
Answer: There are 3.25 or 3 1/4 gallons in one cooler
Step-by-step explanation:
If one liter is appx .26 gallons we need to multiply the number of liters there are. So 12.5 times .26 to get the answer 3.25
<span>Number of Polygon Sides = (Sum of Interior Angles ÷ 180) + 2
= (2,700 / 180) + 2
15 + 2
The answer is 17 sides

2x² = 7x + 6
Subtract both terms so that we can get 0 on one side.
2x² - 7x - 6 = 0
Find what factors of - 12 (2 * - 6) add up to be - 7. It's - 4 and - 3.
2x² - 4x - 3x - 6 = 0
2x(x - 2) - 3(x - 2) = 0
(x - 2)(2x - 3) = 0
Now set each equal to 0.
x - 2 = 0
x = 2
2x - 3 = 0
2x = 3
x = 3/2
x = 3/2, 2
S=saving
X=amount left
S-55=x
Another way : x=s-55
