Question

If b represents the number of blue bikes, which variable expression represents the phrase: 'The sum of the number of blue bikes and the 9 red bikes'?

Answer 1

The variable expression that represents the phrase 'The sum of the number of blue bikes and the 9 red bikes' is b + 9.

Step-by-step explanation:

The variable expression that represents the phrase 'The sum of the number of blue bikes and the 9 red bikes' is b + 9.

The variable b represents the number of blue bikes, and the number of red bikes is given as 9. To find the sum of these two numbers, we simply add them together.

For example, if b = 5 (number of blue bikes), then the sum would be 5 + 9 = 14 (blue bikes + red bikes = total bikes).
