Answer:
32year
Step-by-step explanation:
let Ahmed be x years then sheriff will be x+8
in 7years time
sheriff will be x+8+7=x+15
Then Ahmed will be x+7
sum of their ages will be 7\10×100=70years
x+15+x+7=70
collect like terms
2x+22=70
2x=70-22
2x/2=48/2
x=24years
Sheriff=24+8
32years
Answer:
0 < x < 2.5
Step-by-step explanation:
-16x² + 38x + 5 = 0
-16x² + 40x - 2x + 5 = 0
-8x(2x-5) - 1(2x-5) = 0
x = -⅛ , 2.5
0 < x < 2.5
If it doubles in every 4 months, then in 1 year it will double by 12/4 = 3 times.
So, the expression would be: n³
n = number of rabbit at starting point = 8
So, after 1 year, it would be = 8³ = 512
So, your final answer is 512
Hope this helps!
Yes because 3*4x is 12x and 3*8 is 24 so you would get 12x+24
