Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.
The supplementary angle would be 180 degrees, and the other angle would be 92.2 degrees
To solve, set up a proportion
3.25 cups x cups
---------------- = ---------------
13 servings 28 servings
Now cross multiply
13x = 28 * 3.25
Simplify.
13x = 91
Divide both sides by 13
x = 7 cups
To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
Interpret the exponent in the formula. S to the third power means to use s as a factor 3 times.
V = S to the third power = S x S x S
Find the volume of the first cube.
Substitute 4 for s.
V = 4 x 4 x 4 = 64
Find the volume of the second cube.
Substitute 7 for s.
V = 7 x 7 x 7 = 343
Tamara's first cube has a volume of 64 cubic centimeters, and her second cube has a volume of 343 cubic centimeters
