Question

change word phrase to an algebraic expression

the difference between three times a number and 7

Answer 1

So the word "difference" in math means subtraction do you know where to start?

Answer 2

no
i had this 3(x+7)

Answer 3

can anyone help

Answer 4

OKay I think The answer is (3*x) - 7

Answer 5

Do you understand why though?

Answer 6

nope

Answer 7

3x-7 (like Kezia said) because when it says a number it means a variable, or x because it could be any number. Difference would be x in 8-2=x. It's the amount of number distance (number distance? lol) between two numbers. I can explain it differently if you still don't get my wording.

Answer 8

So then (3*x) is for the 3 times a number

Answer 9

and the difference between that 3x and 7.
