Step-by-step explanation:
Answer:
n =4
Step-by-step explanation:
6x^n• 4x^2=24x^6
Combine like terms
24 x^n *x^2 = 24 x^6
We know that a^b * a^c = a^(b+c)
24 x^(n +2) = 24 x^6
Divide each side by 24
x^(n +2) = x^6
The bases are the same so the exponents are the same
n+2 = 6
Subtract 2
n+2-2 = 6-2
n=4
Answer:
Step-by-step explanation:
<u>Mark</u>
- Initial amount - $200
- Earning - $20*j
- Saving is: S = 20j + 200
<u>Ryan</u>
- Initial amount - $350
- Earning - $15*j
- Saving is: S = 15j + 350
<u>If they get same saving, then the equations will be equal:</u>
- 20j + 200 = 15j + 350
- 20j - 15j = 350 - 200
- 5j = 150
- j = 150/5
- j = 30
The answer is 30 mowing jobs

Step-by-step explanation:
Given system of equations are
2x-6y-2z = 1
3y - 2z = -5
2y + 2z = -3
given
2 x - 6 y - 2 z = 1
0 x + 3 y - 2z = -5
0 x +2y + 2 z = - 3
