Answer:
(1680)
Step-by-step explanation:
Simplify the following:
3 (10 (6 + 2 (22 + 8) - 10))
| 1 |
| 2 | 2
+ | | 8
| 3 | 0:
3 (10 (6 + 2×30 - 10))
2×30 = 60:
3 (10 (6 + 60 - 10))
6 + 60 = 66:
3 (10 66 - 10)
| 6 | 6
- | 1 | 0
| 5 | 6:
3 (10×56)
10×56 = 560:
3 (560)
3 (560) = (3×560):
(3×560)
3×560 = 1680:
Answer: (1680)
5y+2(3y-1)=__y-(y+2)
5y+6y-2=__y-y-2
11y-2+2+y=__y
12y=___y
so 12

Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
[(4096)⁰]⁻⁴ = (4096)⁰ = 1
