What is the mathematical average of the number of weeks in a year, seasons in a year, and the number of days in January?

mean = sum of values/total number of values

(52 weeks, 4 seasons, 31 days in January)

mean = (52+4+31)/3; mean = 87/3; mean = 29

(52 weeks, 4 seasons, 31 days in January)

mean = (52+4+31)/3; mean = 87/3; mean = 29

Determine the grams

1. Given grams/Given ounces= # Grams

2. Last total x ounce equal to= total

2. Last total x ounce equal to= total

If the perimeter of a rectangular house is 44 yards and the length is 36 feet what is the width of house?

P = 2L + 2W (convert P to ft and sub known values)

132 = (2*36) + 2W (simplify)

132 = 72 + 2W (subtract 72 from each side of the equation)

60 = 2W (divide both sides of the equation by 2 to find the width)

30 = W

132 = (2*36) + 2W (simplify)

132 = 72 + 2W (subtract 72 from each side of the equation)

60 = 2W (divide both sides of the equation by 2 to find the width)

30 = W
