Answer:

Step-by-step explanation:

let present age of

Dylan=x

Renee=y

x+y=57

9 years ago

x-9=2(y-9)=2y-18

x=2y-18+9=2y-9

so  2y-9+y=57

3y=57+9=66

y=66/3=22

x+22=57

x=57-22=35

Dylan's present age=35 years

The first time a census was taken in Esinville, the population was 12,621. Each year after that, the population was about 6% hig
Sedbober [7]
Step-by-step
Population was 12.621 when it was measured

Next year it rose by 6%, so add that 6% to 100% and multiply with population measured

12.621 × (100%+6%) = 12.621 × 106% = 13.379,24

Since a man cant be 0,24, we count that as +1

13.379,24 = 13.379 + 1 = 13.380

That was for a year after measurement, now let's calculate for another year
Now, add those 6% to a new population number

13.380 × (100%+6%) = 13.380 × 106% = 14.182,8

since 0,8 isn't a man, instead we add again +1

14.182,8 = 14.182 + 1 = 14.183

now let's do it for another year after last, by adding those 6% to a newest population number

14.183 × (100%+6%) = 14.183 × 106% = 15.033,98

round it again to +1, since 0.98 isn't a man

15.033,98 = 15.033 + 1 = 15.034

that is it, now graph is in the picture.
