Let x be the population of Chicago.

We are given that the population of New York City is 18.8 million people, which is about 9.9 million more than the population of Chicago.

Therefore, we can write the equation as:
18.8 = x + 9.9

Solving for x, we get:
x = 18.8 - 9.9
x = 8.9 million

Therefore, the approximate population of Chicago is 8.9 million people.

Correct response: 8.9 million
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+468=129
x plus 468 equals 129

x−129=468
x minus 129 equals 468

x−468=129
Let x be the height Cheyenne's brother climbed up the mountain.

We are given that Cheyenne climbs 468 feet, which is 129 feet more than her brother climbs.

Therefore, we can write the equation as:
468 = x + 129

Solving for x, we get:
x = 468 - 129
x = 339 feet

Therefore, Cheyenne's brother climbed up the mountain to a height of 339 feet.

Correct response: x + 129 = 468
