Answer:
x=-8
Step-by-step explanation:
550+450-120+720=1,600
720/1,600*100%
=720/160%
=45%
therefore, 45% of new balance
Answer:
7 to the power of 2 - 2 * 3 is equal to 43
Step-by-step explanation:
In my estimations you have a triangle with 2 angles and an altitude or height. You have to find the base of the triangle in order to find the area. I set up the triangle and sine the 60 degree angle was bisected I know that the vertex angle is 30 in my right triangle. I used the tangent ratio of 30 to find the base of that triangle and then multiplied it by 2 to get that the whole base measure is 27.71281292. Then I multiplied it by the height I was given of 24 and divided the whole mess in half to get the area. 332.553 units squared.
125 %
If you divide 15 by 12 (the difference between the prices) then that's what you get :)
