Answer:
x = 9/25
y = 7/25
z = 4/25
Step-by-step explanation:
2x + y = 1 .......(1)
3y + z = 1 ........(2)
x + 4z = 1 ........(3)
Elimination 1 and 2
2x + y = 1 | ×3 |
3y + z = 1 | ×1 |
6x + 3y = 3
3y + z = 1
___________--
6x - z = 2 .............. (4)
Elimination 3 and 4
x + 4z = 1 | ×6 |
6x - z = 2 | ×1 |
6x + 24z = 6
6x - z = 2
___________--
25z = 4
z = 4/25
Elimination 3 and 4
x + 4z = 1 | ×1 |
6x - z = 2 | ×4 |
x + 4z = 1
24x - 4z = 8
___________+
25x = 9
x = 9/25
Subsitution 1
2x + y = 1
2(9/25) + y = 1
18/25 + y = 1
y = 1 - 18/25
y = 25/25 - 18/25
y = 7/25
Answer:
for the seniors, the answer is $12, and for the children, the answer is 8.
Step-by-step explanation:
Answer:
(x - 1) (3 x - 8)
Step-by-step explanation:
Factor the following:
3 x^2 - 11 x + 8
Factor the quadratic 3 x^2 - 11 x + 8. The coefficient of x^2 is 3 and the constant term is 8. The product of 3 and 8 is 24. The factors of 24 which sum to -11 are -3 and -8. So 3 x^2 - 11 x + 8 = 3 x^2 - 8 x - 3 x + 8 = 3 x (x - 1) - 8 (x - 1):
3 x (x - 1) - 8 (x - 1)
Factor x - 1 from 3 x (x - 1) - 8 (x - 1):
Answer: (x - 1) (3 x - 8)
