Sherrie receives 5 times as many phone calls as carrie, and carrie receives 5 less calls than mary. if the total number of combined calls for them was 68 how many calls did mary receive?

let g, r and l be the calls received,

r=c−5 and g=5b=5(c−5)=5c−25

So, g+r+l=7c−30=68,
7c = 98. c = 14

Mary received 14 calls.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

i believe that the slope of the line is -5
