In a recent international sport competition, the top 3 countries— country a, country b, and country c— won a total of 134 medals. country b won 9 more medals than country c. country a won 36 more medals than the total amount won by the other two. how many medals did each of the top three countries win?

Country A = 85, Country B = 29, Country C = 20

Step-by-step explanation:

A+B+C=134 eq(1)

B=C+9 eq(2)

A=36+B+C eq(3)

By substituting eq(2) in eq(3), we get:

A=36+C+9+C

A=2C+45 eq(4)

Now substituting eq(2) & eq(4) in eq(1), we get

2C+45+C+9+C=134

4C+54=134

4C=134-54

4C=80

C=20

Now putting the value of C in eq(2),

B=20+9

B=29

Substituting the value of B & C in eq(1), we get:

A+29+20=134

A+49=134

A=134-49

A=85

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
