Cos x = 15÷17
because cos is adjacent side over hypotenuse.
Answer:
x = 32
Step-by-step explanation:
x + 10 = 42, then you subtract 10 from both sides to get 32
They will make the same amount after 10 phones sold. Before that Plan A is the better plan. After 10, Plan B is the better plan.
You can find the point of intersection by modelling the two equations and setting them equal to each other. If x is equal to phones sold:
250 + 25x = 50x
250 = 25x
10 = x
Therefore, you make the same at 10 phones.
3/2 We look for a number that goes into both 9 and 6 without leaving a remainder, and that number is 3
you can conclude that lines A and B are parallel to each other
