Answer:
Easy, all you have to do is add em all together 80+70=150 and 2+6=8 so 150+8=158
Step-by-step explanation:
The answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24
6m+6n=-30
6m-5n=14
11n=-44
n=-4
m=-1
Ordered pair is (-1,-4)
