Question

Diego scored 6 points less than Monica on a Math

test. The sum of their scores was 188. If x
represents Monica's score, which equation models
the relationship between their scores ?

A. X – 6 = 188
B. x + 6 = 188
C. x + (x – 6) = 188
D. x + (x + 6) = 188

Answer 1

C. x + (x – 6) = 188

Explanation:

if x represent Monica's score

then the score of Diego is x - 6

therefore

Monica's score + Diego`s score = 188

means

x + (x - 6) = 188
