At the per fair, darlene's dog weighed 5 times as much as leah's dog. together, the dogs weighed 84 pounds. how much did each dog weigh? complete the bar model. write an equation and solve

A) Dd + Ld = 84

B) Dd = 5*Ld      

B) -Dd +5 * Ld = 0  Then adding A) and B)

6 * Ld = 84

Leah's Dog = 14 pounds

Darlene's Dog = 84 -14 = 70 pounds

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
