Answer:
(2, 9)
x = 2
y = 9
Step-by-step explanation:
To solve this system, we can either use substitution or graph it. I will be showing how to graph it.
To solve by graphing, we graph both of the equations and find the point at which the lines intersect.

I'm sorry the picture is blurry. Could you post another one.
This is the formula you would use to calculate how many tiles you would need.
# of tiles you need = Total square footage ÷ square footage of each tile
Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet
# of tiles you need = 4761 ÷ 4 = 1190.25
You will need 1190.25 tiles.
To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.
3/4-(3/10+1/4)
Step 1:Change the denominators so that way they are all the same
3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20
Step 2: Begin solving the problem
6/20+5/20=11/20
15/20-11/20=4/20
Step 3: Simplify your answer
4/20=1/5
Step 4 (is optional): Write your answer in a complete statement
The three girls walk 1/5mile together to school
Answer: A
I hope this is correct and if not I apologize for giving false information.
