When Joey mowed lawns for 10 hours and walked dogo
1 answer:
The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.
Step-by-step explanation:
Let,
x be the charge per hour for mowing lawns
y be the charge per hour for walking dogs
According to given statement;
10x+4y=62 Eqn 1
8x+5y=55 Eqn 2
Multiplying Eqn 1 by 5
Multiplying Eqn 2 by 4
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 18
Putting in Eqn 1
Dividing both sides by 4
The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.

Answer:
(-4, -3)
Step-by-step explanation:
The graph of both lines will be shown below.
To find the solution, we need to find the point on the graph that both lines intersect on.
As we can see, both lines intersect on the point (-4, -3). Thus, that is the solution.
Best of Luck!
