The population of a small coastal resort town, currently 2,600, grows at a rate of 4% per year. This growth can be expressed by the exponential equation P = 2,600(1 + 0.04)t, where P is the population after t years. Find the number of years it will take for the population to reach 10,000. Round your answer to the nearest tenth.

a - base

b - exponent

so,

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
