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?
thats wrong its x + 129 = 468!
Let's call the height that Cheyenne's brother climbed "x".
According to the problem, Cheyenne climbed 129 feet more than her brother, so her height climbed can be represented as "x + 129".
And we know that Cheyenne climbed a total of 468 feet, so we can set up the equation:
x + 129 = 468
To solve for x, we can subtract 129 from both sides:
x = 339
Therefore, Cheyenne's brother climbed 339 feet up the mountain.
