Let x represent the number of ounces of blueberries that Wayne bought.
He used 3/8 of the blueberries to make blueberry bread. This means that the amount of blueberries that he used to make blueberry bread is 3x/8 ounces
He used 1/6 of the blueberries to make pancakes. This means that the amount of blueberries that he used to make pancakes is x/6 ounces.
He used 5/12 of the blueberries to make jam. This means that the amount of blueberries that he used to make jam is 5x/12 ounces. The total amount of blueberries used is
3x/8 + x/6 + 5x/12 = 46x/48
If Wayne uses 69 ounces of blueberries he bought, it means that
Perimeter is gotten by adding up the length/height of every side of the polygon (1.5in + 1.5in + 0.75in + 0.75in), while the Area of a rectangle is gotten by multiplying the height and length. (1.5in × 0.75in)
