Translate the word phrase into a math expression. nine more than five times a number A. 9 > 5n B. 9 – 5n C. 5n – 9 D. 5n + 9
It says that b represents Becky’s score and c represents Cathy’s score.
Becky’s score was 5 less than Cathy’s score, its equation can be written as :-
b = c - 5
It says that their combined score totaled 185, its equation can be written as :-
b + c = 185
So, correct pair of equations is b = c - 5 and b + c = 185.
If Becky’s score was 5 less than Cathy’s, then we would write:
b = c - 5
If Becky’s and Cathy’s scores add up to 185, then we would write:
b + c = 185
These are the two equations:
b = c - 5
b + c = 185
