Which of the following choices translates the sentence “the difference of three times a number and 20 is 13”?

evablogger [386]

Answer:

3x - 20 = 13

Step-by-step explanation:

1. The word is signals the equal sign.

The difference of three times a number and 20 = 13

2. The word difference signals subtraction.

3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.

4. Three times that number = 3x.

The difference = subtraction.

3x-20=13
