Question

michael starts mountain biking at an elevation of -100 feet and bikes up to an elevation of 50 feet. what was michaels change in elevation while mountain biking? create an equation to represent the situation. use x to represent michaels change in elevation while mountain biking. boxes and options: x, -100, 100, ·, +, =, 50

Explanation:

Step1: Define initial and final elevation

Initial elevation is -100 feet, final is 50 feet. Let \( x \) be change in elevation.

Step2: Form the equation

The equation is initial elevation + change in elevation = final elevation, so \( -100 + x = 50 \).
To find \( x \), solve \( x = 50 - (-100) = 50 + 100 = 150 \).

Answer:

The equation is \(-100 + x = 50\) and the change in elevation is 150 feet.
