Help with the step by step
Nataliya [291]

Step-by-step explanation:

First, distribute the -4 to the parenthesis:

24a-22=-4+24a

Add 22 to both sides:

24a-22+22=-4+22+24a

Simplify:

24a=18+24a

Subtract 24a from both sides:

24a-24a=18+24a-24a

Simplify:

0=18

hope this helps :)

MAVERICK [17]

Answer:

The population is all the adult men who are 40 to 60 years of age and live in the United Stades.

Step-by-step explanation:

The population is all the adult men who are 40 to 60 years of age and live in the United Stades.

The 1338 are the sample, and the study wants to find the proportion of all these adults who had seen their family doctor. Since 1338 is a large sample size, this proportion can be extended to all the adult men who are 40 to 60 years of age and live in the United Stades.

An online store sells old video games and DVDS as a bundle. A bundle of two video games and three DVDS can be purchased for $89.
irga5000 [103]

Answer:

video game: $29.50

DVD: $10

Step-by-step explanation:

Let d = price of one DVD, and let v = price of 1 video game.

"A bundle of two video games and three DVDS can be purchased for $89.00."

2v + 3d = 89

"A bundle of one video game and two DVDS can be purchased for $49.50."

v + 2d = 49.5

We have two equations in two unknowns, so we can solve them as a system of 2 equations.

2v + 3d = 89

v + 2d = 49.5

Rewrite the first equation.

Multiply both sides of the second equation by -2 and write it below the first equation.

Add the equations.

       2v + 3d = 89

(+)   -2v - 4d = -99

---------------------------

               -d = -10

d = 10

Now we substitute 10 for d in the second original equation and solve for v.

v + 2d = 49.5

v + 2(10) = 49.5

v + 20 = 49.5

v = 29.5

Answer: video game: $29.50; DVD: $10
