Answer:
x = 13/25
Step-by-step explanation:
- 4 (9 - 7x) - (1 - x) = 4 (x - 6)
- 36 + 28x - 1 + x = 4x - 24
28x + x - 4x = - 24 + 36 + 1
25x = 13
x = 13/25
Answer:
(2,-1) and 5
Step-by-step explanation:
1. A (x²-4y)³
2. ?=5
3. (x+3)(3y-5)
4. (4y+7)(5x-1)
Answer:
y=11
Step-by-step explanation:
To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.
To Check your answer:
Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.
Answer:
V = 896 pi m^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
We know the radius is 8 and the height is 14
V = pi (8)^2 * 14
= pi *896
