Answer: 23 cups
Step-by-step explanation:
There were 4 groups with 5 people each and all of them ordered a cup of hot chocolate:
= 4 * 5
= 20 cups
Rebecca, Malaki, and Jeffrey each ordered an extra cup of hot chocolate so that's 3 extra cups:
= 20 + 3
= 23 cups
1w-4= 4-1w
+1w +1w
——————
2w-4=4
+4 +4
—————
2w=8
———
2. 2
w= 4

When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).
The reciprocal of z^-3 would be 1 / z^3.
