Just plug in the numbers for the variables
![a. \: 1 + ( - 4) + ( - 3) \\ b. \: 1 + ( - 4) - (2 \times ( - 3)) \\ c. \: 1 + (3 \times ( - 4)) - (2 \times ( - 3))](https://tex.z-dn.net/?f=a.%20%5C%3A%201%20%2B%20%28%20-%204%29%20%2B%20%28%20-%203%29%20%5C%5C%20b.%20%5C%3A%201%20%2B%20%28%20-%204%29%20-%20%282%20%5Ctimes%20%28%20-%203%29%29%20%5C%5C%20c.%20%5C%3A%201%20%2B%20%283%20%5Ctimes%20%28%20-%204%29%29%20-%20%282%20%5Ctimes%20%28%20-%203%29%29)
Does this help?
17 + 15 + 26 = 58 (he wants 58 tickets)
22 - 8 = 14 (he has 14 tickets)
58 - 14 = 44 (he needs 44 tickets)
The answer to your question is A
Answer: 14
Step-by-step explanation:
Since it is a right angles triangle , Pythagoras theorem will come into play,which states that;
the square of the hypotenuses = square of the adjacent + square of the opposite , that is
=
+ ![17^{2}](https://tex.z-dn.net/?f=17%5E%7B2%7D)
Therefore:
=
- ![17^{2}](https://tex.z-dn.net/?f=17%5E%7B2%7D)
= 484 - 289
= 195
RT = ![\sqrt{195}](https://tex.z-dn.net/?f=%5Csqrt%7B195%7D)
RT = 13.96
RT≈ 14
