A TV station wants to conduct a survey to determine which sport should be shown on Sunday in the viewing area: a football game or a baseball game. Which of the following samples would be a fair representation of people to ask? A. Sample 1: 50 high school football players and 50 high school baseball players B. Sample 2: 50 boys and 50 girls at the local middle school C. Sample 3: 100 people who were preselected because they do not watch sports D. Sample 4: every 100 thperson at a local shopping mall

I'm not completely sure about this. The answer is B.) Sample 2: 50 boys and 50 girls at the local middle school. :)

Step-by-step explanation:

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
