Special attention 5 less than x

Practice Examples: – four more than six times a number – half the difference between a number and three – the quotient of seven and a number

Practical Formulas A = lw (Area of a Rectangle) P = 2l + 2w (Perimeter of a Rectangle) D = rt (Distance equals rate times time) C = np (Cost equals number of items times price per item)

Examples: a.Find the area and perimeter of a rectangle with length 4 and width w. b.You buy 6 pencils at m cents each and 4 notebooks at n cents each. How much did you spend? c. You travel 40 miles per hour for x hours. How far did you travel?
