Can someone solve 5 + 2x = + 6 and n - 3n = 14 - 4n and 7 ( 5a - 4 ) - 1 = 14 - 8a

professor190 [17]

Answer:

5 + 2x = 6

2x = 6-5

2x = 1

x = 0.5

n -3n = 14 -4n

-2n = 14-4n (since 4n is negative, change the sign to make it positive and then add 4n to both sides of the equation)

2n = 14

n = 7

7 (5a - 4) - 1 = 14 - 8a

35a - 28 - 1 = 14 -8a

35a -29 = 14 - 8a

43a = 43

a = 1

krek1111 [17]

Answer:

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen

Step-by-step explanation:

we know that

The population density is the number of people per unit of area

Find out the population density for each region

Bear Creek

$\frac{462}{112}= 3.70\ people/acre$

Binky Lee

$\frac{12,624}{3,412}= 4.13\ people/acre$

Cheslen

$\frac{3,537}{1,263}= 2.80\ people/acre$

Crow's Nest

$\frac{2,142}{612}= 3.5\ people/acre$

Cheslen < Crow's Nest < Bear Creek < Binky Lee

therefore

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen
