WHAT EQUATION REPRESENTS THE FOLLOWING REAL-WORLD PROBLEM? CHEYENNE CLIMBS 468 FEET UP A MOUNTAIN. THIS IS 129 FEET MORE THAN HER BROTHER CLIMBS. HOW HIGH DID CHEYENNE'S BROTHER CLIMB UP THE MOUNTAIN?
Let's represent the height that Cheyenne's brother climbed with variable "x". Since Cheyenne climbed 129 feet more than her brother, the equation would be:
x + 129 = 468
Therefore, the equation that represents the real-world problem is x + 129 = 468.
