Answer:
x = 1/4 k
Step-by-step explanation:
11kx + 13kx = 6
(11k+13k)x = 6
24kx = 6
x = k/4

Answer and step-by-step explanation:
15. 7(8+t) -5t
Break the bracket, we got:
= 7*8 + 7*t - 5t
= 56 + 7t - 5t
= 56 + 2t or 2 (28 + t)
16. 4n - 2n = 84
2n = 84
Divide both side by 2:
2n / 2 = 84 / 2
n = 42
17. y + 3y = 96
4y = 96
Divide both side by 4:
4y / 4 = 96 / 4
y = 24
18. 5p - 2p = 51
3p = 51
Divide both side by 3:
3p / 3 = 51 / 3
p = 17
Hope this helped :3
Step-by-step explanation:
a)
<u>The first laptop</u>
- Initial value- $2000
- Value loss - 14% every year
- Function for value- V(t) = 2000*0.86^t
<u>The second laptop</u>
- Initial value- $1200
- Value loss - 11% every year
- Function- V(t) = 1200*0.89^t
b)
Monthly percent decrease
<u>The first laptop:</u>
<u>The second laptop:</u>
c)
The second laptop will lose less value in 5 years hence is better choice
