7.50 * 3 = 22.50
305 - 22.50 = 282.50
At the end of 3 months, Javiers account would be $282.50

I think you divide or multiply
Answer:
this one is a glitch in khan academy its broken
Step-by-step explanation:
The sum of all the interior angles in a 5 sided polygon is 540°
simply add up all the known angles, 100+102+108+121=431
540-431=109
x=109° (thanks for providing the degree symbol)
Answer:
Is not possible to compute the angle under those conditions.
Step-by-step explanation:
You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.
Let ΔABC and ΔDEF be two triangles where AB = DE and AC = DF if
∠A > ∠D then BC > EF, which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.
Therefore, there is information missing in order to solve the question
