Two 5-pound bags of oranges and one 8-pound bag of oranges are being shared equally by three friends. Which expression can be evaluated to find the number of pounds oranges each person will get?

(5 + 5 + 8 ) / 3 = x

Step-by-step explanation:

In order to calculate this we must first combine the like terms, which in this case are the three bags of oranges. Once we have that we can divide that number by the amount of friends in order to get an equal amount of oranges that each friend will receive. This can all be done with the following expression where x is the amount each friend will receive.

(5 + 5 + 8 ) / 3 = x

18 / 3 = x

6 = x

So we can see that each friend will receive a 6-pound bag of oranges.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
