Question

ahmed starts rock climbing at an elevation of -100 feet and rock climbs up to... what was ahmed’s change in elevation while rock climbing? what does your answer of x = 150 represent? -100 + x = 50 x = 50 - (-100) x = 50 + 100 x = 150 ahmed rock climbed for 150 minutes. ahmed’s elevation increased by 150 feet. ahmed’s final elevation was 150 feet.

Explanation:

In the equation \(-100 + x = 50\), \(x\) represents the change in elevation. The initial elevation is \(-100\) feet, and the final elevation is \(50\) feet. Solving for \(x\) gives the amount by which the elevation changed. The first option is incorrect as \(x\) is not about time. The third option is incorrect because the final elevation is \(50\) feet, not \(150\) feet. So \(x = 150\) represents the increase in elevation.

Answer:

Ahmed's elevation increased by 150 feet.
