Answer:
y=3x
Step-by-step explanation:

Total students = 375 + 405 = 780
boys % = (375 / 780) *100%
=48.1 %
Add the two functions together to get
7y=-3
y=-3/7
Then plug in y to either function to solve for x, I’ll just use the left one
15(-3/7)-9x=-9
-45/7-9x=-9
-9x=-18/7
x=18/7/9
x=2/7
Answer:
Step-by-step explanation:
Let x represent the number of cars that Jamie washes.
Let y represent the number of pies that Stella makes.
The amount of money needed by Jamie and Stella to sign up for the trip is $600 each
Jamie earns $25 for each car washed. This means that if he washes x cars, he would earn 25×x =$25x
Stella earns $15 for each pie made.
This means that if she makes y pies, she would earn 15×y =$15y
Part 1) The inequality is
25x greater than or equal to 600
Part 2)The inequality is
15y greater than or equal to 600
Part 3) Stella only has enough supplies to make 40 pies. Total amount made from 40 pies would be 40×15 = 600
Jamie's earnings is
25x greater than or equal to 600
Stella's earnings is
15y lesser than or equal to 600
Part 4) Maximum amount of money that Stella can earn is 15×40 = $600
Therefore, Stella can afford to sign up for the trip.
