Answer:
28 degrees
Step-by-step explanation:
147 - 119 = 28
1 7/8 = 15/8
1 1/2 = 3/2
15/8 = 24/16
3/2 = 30/16
24/16 - 30/16 = -6/16, which can be simplified to -3/8
Hope this helped! If you need any explanation, let me know :)
Add each term and divide it by 2.
5+7 = 12
12/2 = 6
-2 + 6 = 4
4/2 = 2, then add the i back on to get 2i.
The midpoint is 6 + 2i
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
12y-3=3
4y+10=2
28y-8=4
30y+18=6
