Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
Answer: well 56 is the answer
Step-by-step explanation:
Answer:
Answer is ...Obtuse
Step-by-step explanation:
![\frac{m](https://tex.z-dn.net/?f=%20%5Cfrac%7Bm%3CABC%7D%7B2%7D%20%20%3D%20m%3C%20CBD)
![\frac{5x + 4}{2} = \frac{3}{2} x + 21](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%20%2B%204%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B2%7D%20x%20%2B%2021)
![\frac{5x + 4}{2} = \frac{3x + 42}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%20%2B%204%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B3x%20%2B%2042%7D%7B2%7D%20)
![5x + 4 = 3x + 42](https://tex.z-dn.net/?f=5x%20%2B%204%20%3D%203x%20%2B%2042)
![5x - 3x = 42 - 4](https://tex.z-dn.net/?f=5x%20-%20%203x%20%3D%2042%20-%204)
![2x = 38](https://tex.z-dn.net/?f=2x%20%3D%2038)
![x = 19](https://tex.z-dn.net/?f=x%20%3D%2019)
![substituting \: x = 19 \: \:in \: \: \: \: \: \: \: \\ m](https://tex.z-dn.net/?f=substituting%20%5C%3A%20x%20%3D%2019%20%20%5C%3A%20%5C%3Ain%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%5C%5C%20m%3CABC%20%3D%5C%3A%20%20%20%5C%3A%205x%20%2B%204%2C%20)
We get,
m<ABC =
![(5 \times 19) + 4 = 99](https://tex.z-dn.net/?f=%285%20%5Ctimes%2019%29%20%2B%204%20%3D%2099)
Hence <ABC is obtuse
2 x - 5y = 13
2 × -1 - 5 × -3 = 13
Answer:
(-1, -3)
Answer:
D
Step-by-step explanation:
The given angles are vertically opposite and congruent , then
7x + 13 = 48 ( subtract 13 from both sides )
7x = 35 ( divide both sides by 7 )
x = 5 → D
