Question

multiple choice 2 points solve the linear equation. -24 - 3x = 3 no solution x = -9 x = -7 x = 9 x = 7 multiple choice 2 points the 2002 american community survey sponsored by the u.s. census bureau projects the population of north carolina as 8,063,874, with 21.2% representing african americans. what is the best estimate of the african american population of north carolina using these statistics? 1,709,541 1,794,541 1,465,541 1,675,451 1,654,441

Explanation:

Question 25

Step1: Add 24 to both sides

$-24 - 3x+24=3 + 24$
$-3x=27$

Step2: Divide both sides by - 3

$\frac{-3x}{-3}=\frac{27}{-3}$
$x=-9$

Step1: Convert percentage to decimal

$21.2\%=0.212$

Step2: Multiply total population by decimal

$8063874\times0.212 = 1709541.288\approx1709541$

Answer:

$x = - 9$
