Question 879125: if 48m+48n=2880 what is the average of m and n?

(Average of m and n) = %28m%2Bn%29%2F2

48m%2B48n%22%22=%22%222880

48%28m%2Bn%29%22%22=%22%222880

Divide both sides by 48

48%28m%2Bn%29%2F48%22%22=%22%222880%2F48

m%2Bn%22%22=%22%2260

(Average of m and n) = %28m%2Bn%29%2F2

Substitute 60 for m+n in %28m%2Bn%29%2F2 = 60%2F2 = 30
