An airplane flies from Metro City to Gotham with a tailwind that increases its normal speed by 80 mph On the return trip, the plane must fly against this wind, which
decreases its normal speed by the same amount. The flight from Metro City takes 2.09
hours and the return trip takes 3.33 hours. How far is it from Metro City to Gotham?

b) well because you get well

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
