Diana said: One-third of a number is 5 less than half of the same number. What is the number? Click to expand... a) Pick a variable to stand for "the number". b) Write an expression, using the variable from (a), for "one-third of the number". c) Write an expression, using the variable from (a), for "half of the number". d) Write an expression, using the expression from (c), for "five less than" the expression from (c). e) Write an equation, using the expressions from (b) and (d), noting that "is" means "equals". f) Solve for the variable. If you get stuck, please reply showing how far you have gotten. Thank you. Eliz.
