Answer:
$15
Step-by-step explanation:
Nelson family:
y = 5x + 40
Jackson family:
y = 10x + 15
Where,
y = Amount paid
x = number of visits
if each family visits the pool 8 times during the summer?
Nelson family:
y = 5x + 40
= 5(8) + 40
= 40 + 40
= 80
y = $80
Jackson family:
y = 10x + 15
= 10(8) + 15
= 80 + 15
= 95
y = $95
What is the difference between what the Nelson family pays and what the Jackson family
Difference = $95 - $80
= $15
Answer:
Replace all occurrences of y with 6x−3 in each equation.
Replace all occurrences of y in 18x−3y=9 with 6x−3 .
18x−3(6x−3)=9
y=6x−3
Simplify 18x−3(6x−3).
9=9
y=6x−3
Remove any equations from the system that are always true.
y=6x−3

Answer:
(3x-2)(3x+2)
When multiplied out it equals the original expression
Answer:
1092 people attended the last basketball game.
Step-by-step explanation:
Given that:
Number of people who attended the first basketball game = 840
Percent increase for last game = 30%
Total people who attended last game = (100+30)% = 130% of first game
Number of people who attended last game = 
Number of people who attended last game = 1.30*840 = 1092
Hence,
1092 people attended the last basketball game.
