Step-by-step explanation:
We must ask a question that your answer corresponds to each of the topics in the statement, therefore we will review each one:
5. Distances members of the track team jogged last week
How far did you run last week?
6. Numbers of letters in name of street you live on
How many letters are there in the name of your street?
7. Cost of a restaurant dinner
How much did you pay for dinner?
8. Numbers of cars of different colors in a parking lot
What color is your car?
answer.
Answer:
x=2 and y=0 is the required result.
Step-by-step explanation:
We have been given system of equations:
5x+2y=105x+2y=10 (1)
And 3x+2y=63x+2y=6 (2)
We will use elimination method:
Multiply 1st equation by 3 and 2nd equation by 5 we get:
15x+6y=3015x+6y=30 (3)
15x+10y=3015x+10y=30 (4)
Now subtract (4) from (3) we get:
-4y=0−4y=0
y=0y=0
Now, put y=0 in (1) equation:
5x+2(0)=105x+2(0)=10
5x=105x=10
x=2x=2
Hence, x=2 and y=0

It would be 13... if I did my math right.
