Question

ahmed starts rock climbing at an elevation of -100 feet and rock climbs up to an elevation of 50 feet. what was ahmed’s change in elevation while rock climbing? now rewrite the equation using the additive inverse of -100. -100 + x = 50 x = 50 - (-100) x = 100 -100 50 +

Explanation:

Step1: Recall subtraction of negatives

Subtracting a negative is adding its positive: $50 - (-100) = 50 + 100$.

Step2: Add the numbers

$50 + 100 = 150$.

Answer:

$x = 50 + 100$ (and the value of $x$ is 150, but the equation rewrite is $x = 50 + 100$)
