Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:
Buttercup starts with $10 and saves $20 per week. So:
When they have the same amount of money, the two equations will be equal to each other. Therefore:
Solve for x. Subtract 10 from both sides:
Subtract 5x from both sides:
Divide both sides by 15:
Westley and Buttercup will have the same amount of money after 5 weeks.
Answer:
Add equations A + B to eliminate y
Then add equations A and C to eliminate y
Step-by-step explanation:
Since all the equations have y with a coefficient of 2, I would eliminate y
Add equations A + B to eliminate y
Then add equations A and C to eliminate y
Answer:
your answer will be 1.1375×10^12
Answer:
y=-5/2x-3
Step-by-step explanation:
put the 2 points in slope to get -5/2. then use point slope form(y-y1)=m(x-x1) and put -8 in y1, 2 in x1, and -5/2 in m
