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
The GCF is 3*b = 3b
Step-by-step explanation:
The GCF is the Greatest Common Factor which will divide all the numbers whose GCF it is.
To find the GCF, we factorize the polynomials first
So,

We can see that only 3 and b are common in factors of both polynomials
So,
The GCF is 3*b = 3b

Answer:
17
Step-by-step explanation:
let x be the number of boxes to be shaded to make it 80%
x = 80% of total number
= 80/100 of 25
= 80/4
= 20
So 20 need to be shaded to fill 80%
Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13
= 17 squares
18+18=36 so there are 36 cookies altogether
