The thing about that problem is that when the circle is inscribed inside that triangle, the side measures created are doubled. By that I mean that the 9 on the top right is also the measure of the top left. Same thing for the 13 and the 16. The lower left unmarked side length is 13, the lower right side length is 16. Now add it all up: 9+9+13+13+16+16
Answer:

Answer:
Step-by-step explanation:
she had $ 24 to spend on 7 pencils....and after buying them she had $ 10.
this means that the total of the pencils was (24 - 10) = $14
and assuming each pencil cost the same price....
14/7 = $ 2 per pencil
or u can set it up as an equation
24 - 7x = 10....with x being the price of a pencil
24 - 10 = 7x
14 = 7x
14/7 = x
2 = x <==
