so the pair went down from 200 to 140, so the difference is 200 - 140 = 60.
so if we take 200 as the 100%, what is 60 off of it in percentage?

The answer is 36°
Hope that helps, Good luck! (:
-450 and can i get brainliest
You plug in 2x + 4 into the y for the other equation (3x +y ) and solve for it
(300) (30,000) = 9 x 10m
9,000,000 = 90m
divide by 90
100,000 = m
