x = 7
Thus
CD = x = 7
You would do 120 mins divides by 15 miles = 8
1 mile = 8 mins
6 x 8 = 48 mins
Group like terms, in this case terms with variables and terms without. (m + 11) + (n + 44) = (m + n) + (11 + 44) Then simplify. (m + n) + (11 + 44) = (m + n) + 55 = m + n + 55 Final answer: m + n + 55
