Answer:
Step-by-step explanation:
1. Make 1 2/7 an improper fraction = 9/7
2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.
3. Add them together. 14/21+27/21=41/21.
4. (Optional) If the question is asking for mixed numbers, 41/21 = 1 20/21.

Answer:Let x be one of the angles.
Let (180-x) be the other angle we need.
x = (180-x) - 62
2x = 180-62
2x = 118
x = 118/2
x = 59�
180-59 = 121�
The two angles are 59� and 121�.
4a - (3a - 2b) + 3a
4a - 3a + 2b + 3a
a + 2b + 3a
4a + 2b
