An airplane takes off from denver international airport at an altitude of 5430 feet. It reaches its highest cruising altitude of 40,536 feet above the Mojave desert. It lands in Leadville, CO 1 hour and 32 minutes later at an altitude of 9,934 feet. Create an absolute value inequality to represent the airplanes altitude.

answer: 4

step-by-step explanation:

because that’s us why

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

the answer for the second equation is (4,0)
