24 boys started a cycle racc and 18 of them

1 answer:

75% ended the race
25-18=6
6 goes into 24 4 times so it is 25% that did not finish
100%-25%=75%
So 75% finished the race

I'm assuming this is a system of equations you want solved so,

x = -y + 3

-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2

x + 2 = 3
x = -1

(-1,2)

$(3x + 20degrees ) = 180degrees$

180 degress because a stranight angle equals that

Add the equations.

x-y%2B0.5x%2By=7%2B5

1.5x=12

highlight%28x=8%29

Now use either equation to solve for y.

8-y=7

highlight%28y=1%29

x=8

y=1
