A group of 5 friends each have x action figures in his or her collection. Each friend buys 11 more action figures. Now the 5 friends have a total of 120 action figures. How many action figures did each friend start with?

13

how?

subtract 55 from 120 and get 65

divide 65 by 5 to get 13

the answer is 13

Step-by-step:

Subtract 55 from 120 and get 65

Divided 65 by 5 =13

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
