Use Gauss-Jordan row reduction to solve the given system of equations. If the system is dependent, express your answer in terms of y and z, where x = x(y, z).) x + y − 2z = 24
-x -5y/2 = -3/2

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

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
