Answer:
x=14
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−9)=20
Step 1: Simplify both sides of the equation.
4(x−9)=20
(4)(x)+(4)(−9)=20(Distribute)
4x+−36=20
4x−36=20
Step 2: Add 36 to both sides.
4x−36+36=20+36
4x=56
Step 3: Divide both sides by 4.
4x

Answer:
Step-by-step explanation:
This is a simplified solution.
There is 6.74 quarts left in the cooler.
Since 5 of the glasses have a capacity of 0.36 qt, this is a total of 5(0.36) = 1.8 qt. The 8 glasses that have a capacity of 0.52 qt have a total of 8(0.52) = 4.16 qt. This gives a total of 4.16+1.8 = 5.96 qt.
To find the remaining, subtract from 12.7:
12.7-5.96 = 6.74 qt.
