Which of the following algebraic equations models the english sentence, a number decreased by two is equal to four? a. w + 2 = 4 b. 2 − w = 4 c. w − 2 = 4 d. w = 2 − 4.

C. w − 2 = 4

Step-by-step explanation:

We need to find the algebraic equation corresponding to the sentence:

"a number decreased by two is equal to four"

So we can represent "a number" by w

"decreased by two" would be to subtract 2 so - 2

"is equal to four" would be = 4

So the algebraic equation is:

w - 2 = 4

This is answer C
