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.

Figured what out
a question
P(A) = 0.36
P(B) = 0.25
P(A and B) = 0.09
Notice how P(A and B) = P(A)*P(B) = 0.36*0.25 = 0.09
So because P(A and B) = P(A) *P(B) in this case, this means A and B are independent events. In other words, the fact that A occurs does not alter the probability of event B.
Answer: independent
Y = 3x + 10
This equation is written in slope intercept form, which is y=mx+b. M equals the slope and b = the y intercept. So in your case, 3 is the slope and 10 is the y intercept.
I don't know what coordinate form is, but I hope that this helped you a little bit.
