From 2006 to 2010, the population of a town declined to 22,000. The population is expected to continue to decline at a rate of 2
Sphinxa [80]

The population in 2040 of the town can be solved using the formula

F = P( 1 -I)^n

Where F is the future population

P is the present population

I is the decline rate

N is the number of years

F = 22,000(1-0.028)^39

Solve this equation.
spin [16.1K]

Answer:

D: 6 5/6

Step-by-step explanation:

Solve for a:

a + 7/6 = 8

Put each term in a + 7/6 over the common denominator 6: a + 7/6 = (6 a)/6 + 7/6:

(6 a)/6 + 7/6 = 8

(6 a)/6 + 7/6 = (6 a + 7)/6:

(6 a + 7)/6 = 8

Multiply both sides of (6 a + 7)/6 = 8 by 6:

(6 (6 a + 7))/6 = 6×8

(6 (6 a + 7))/6 = 6/6×(6 a + 7) = 6 a + 7:

6 a + 7 = 6×8

6×8 = 48:

6 a + 7 = 48

Subtract 7 from both sides:

6 a + (7 - 7) = 48 - 7

7 - 7 = 0:

6 a = 48 - 7

48 - 7 = 41:

6 a = 41

Divide both sides of 6 a = 41 by 6:

(6 a)/6 = 41/6

6/6 = 1:

Answer:  a = 41/6 or a= 6 5/6

5x - 10 + 65 = 90 what is the value of x?
ki77a [65]

Answer:

x =7

Step-by-step explanation:

Solve for x:

5 x - 10 + 65 = 90

Add like terms. 65 - 10 = 55:

5 x + 55 = 90

Subtract 55 from both sides:

5 x + (55 - 55) = 90 - 55

55 - 55 = 0:

5 x = 90 - 55

90 - 55 = 35:

5 x = 35

Divide both sides of 5 x = 35 by 5:

(5 x)/5 = 35/5

5/5 = 1:

x = 35/5

The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:

Answer:  x = 7
