The width of a rectangle is two-thirds the length, the perimeter of the rectangle is 15. what is the length?

W = 2/3l

15 = 2l + 2w

Because we have a value for w, we'll place it in the second equation.

15 = 2l + 2(2/3l)

15 = 2l + 4/3l

Multiply all terms by 3.

45 = 6l + 4l

Combine.

45 = 10l

Divide both sides by 10.

4.5 = l

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
