What is combining like terms?

Combining like terms is where you add/subtract/multiply/divide like terms to get a more simplified answer.

Step-by-step explanation:

Combine means put together so that could mean add, subtract, multiply, or divide. Like terms are (just what it sounds like) terms that are alike as in with the same variable or even without a variable. Here's an example combining like terms:

Simplify 5x + 4 - 3x + 7.

First find the terms with the variable x which is: 5x and -3x

Combine them by subtracting 3x from 5x because -3x is negative: 5x - 3x = 2x

Find terms without any variable: 4 and 7

Combine them by adding because they are positive: 4 + 7 = 11

Now, the answer is 2x + 11 and it can't be simplified any more because there are no alike terms.

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. :)

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
