The integer that represents this -45.
Answer:
21)11/16
22)n=8
23)b=19.5
Step-by-step explanation:
<span>With five houses every three hours, Brianna will paint 20 houses in 12 hours. 12 hours / 3 hours = 4 'rounds'. 5 houses * 4 rounds = 20 houses.
With three houses every four hours, Nicholas will paint 9 houses in 12 hours. 12 hours / 4 hours = 3 'rounds'. 3 houses * 3 rounds = 9 houses.
So Brianna will paint 20 - 9 more houses than Nicholas, or 11 houses more.</span>
