Mr. Kendall will build a dollhouse bed as a scale model of an actual bed. The actual bed is 40 inches wide and 78 inches long. The width of the dollhouse bed will be 1 1/4 inches. What length should the dollhouse bed have?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

they r 125, and 216

so the sequence goes 1,8,27,64,125,216
