Let x be the population of Chicago.

Then we can write the equation: x + 9.9 million = 18.8 million

Solving for x:

x = 18.8 million - 9.9 million
x = 8.9 million

So, the approximate population of Chicago is 8.9 million.

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−468=129
x minus 468 equals 129

x+129=468
x plus 129 equals 468

x−129=468
x minus 129 equals 468

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

Then we can write the equation: x + 129 = 468

Solving for x:

x + 129 - 129 = 468 - 129
x = 339

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

Response: x + 129 = 468
