Step-by-step explanation:
When dividing exponents of the same base, we can simply subtract the powers so the new power would be 6 / 7 - 2 / 7 = 4 / 7, hence we need to write as a radical. When writing fractional exponents as radicals, the denominator of the fractional exponent is the index of the radical and the numerator is the exponent of the base inside the radical, hence, our answer is .
Answer:
The length is 72 feet.
Step-by-step explanation:
<em>Equations</em>
2L+2W=192
L=3W
<em>Solving/Substitution</em>
2(3W)+2W=192
8W=192
W=192/8=24
L=24*3=72
The length is 72 feet.
The width is 24 feet.

Answer:
2 and a half pizzas were eaten
Step-by-step explanation:
3 pizzas divided into 8 slices is equal to 24 slices. So if 20 slices were eaten, we can do simple math to solve this
There are two ways to do this:
A. divide 20 by 8 to get 2.5
B. subtract a pizza (8 slices) from 20 to get 12. Subtract another pizza (8 more slices) to get 4. The 4 slices left are equal to another half pizza. So in total, there were 2.5 pizzas eaten
