Answer:
x = 12
Step-by-step explanation:
(7x+4)+(2x+5)+(5x+3) = 180
so if you take out the brackets it would be:
7x+4+2x+5+5x+3 = 180
Then you add the similar variables together which would look like:
14x+12=180
Take away 12 from both sides
14x = 180 - 12
14x = 168
Divide 14 from both sides
x = 168/14
x = 12

Direct variation is is when the x and y a direct relation
without constants added or subtracted
With being times by each other
so the only one that meets the definite is the first one
y = 0.5x means y is equal to half of x. So you know that every y is directly related to half of x
