Answer 1

Let x represent the population of Chicago.

x + 9.9 million = 18.8 million

x = 18.8 million - 9.9 million
x = 8.9 million

Therefore, the approximate population of Chicago is 8.9 million.

Answer 2

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?(1 point)
Responses

x+129=468
x plus 129 equals 468

x−129=468
x minus 129 equals 468

x−468=129
x minus 468 equals 129

x+468=129

Answer 3

x + 129 = 468

Therefore, the equation that represents the problem is: x + 129 = 468.
