Answer:

s = 3

Step-by-step explanation:

2[s+3s-3]=18

2(4s-3)=18

8s-6=18

8s=18+6

8s=24

s=24/8

s=3

2[s + 3(s - 1)] = 18

Do the parenthesis because of using PEMDAS.

P=parenthesis

E= exponents

M= multiplication

D= division

A= addition

S= subtraction

(3)(s)=3s

(3)(-1)=-3

2 [ s+3s-3)] =18

2 [4s-3]=18

Multiply the bracket by 2

(2)(4s)=8s

(2)(-3)=-6

8s-6=18

move -6 to the other side

sign changes from -6 to +6

8s-6+6=18+6

8s=24

divide by 8 for both sides

8s/8=24/8

Cross out 8 and 8, divide by 8 and then becomes 1*1*s=s

s=3

Answer: s=3

if a town with a population of 500 doubles in size ever 9 years, what will the population be 36 years from now?
s344n2d4d5 [400]

The population of the town in 36 years would be  8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value
  • R = rate of growth = 100%
  • N = number of years = 36/9 = 4

500 x 2^4 = 8000
