Brainliest answer plus extra points! two planes leaves an airport at the same time, one flying east one flying west. the eastbound plane travels 60 mphslower. they are 3440 mi apart after 4 hr. find the speed of each plane.

Equation:

distance + distance = 2250 miles

3x + 3(x-110) = 2250

6x - 330 = 2250

6x = 2580

x = 430 mph (rate of the westbound plane)

x-110 = 320 mph (rate of the eastbound plane)

PLS MARK BRAINLIEST!!!

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
