1) The variable x represents a value in the set ( 4, 6, 7, 8). Which value of x makes 2 (x-4) +3 =7?
sammy [17]

Answer:

x=6

Step-by-step explanation:

2 (x-4) +3 =7

Subtract 3 from each side

2 (x-4) +3-3 =7-3

2(x-4) =4

Divide each side by 2

2(x-4)/2 = 4/2

x-4 = 2

Add 4 to each side

x-4+4 =2+4

x=6

A random sample of students were surveyed as to how much non-school screen time
GaryK [48]

The percentage of students who spend less than 4 hours a week on screens which reported a grade average below 80 is 50%

Given, we have the report representing children spending time online, on social media or watching T.V, which has there effect on there grades as above or below 80.

By the question we know that the number of students who spends less than 4 hours a week on screen is:

9 + 9

= 18

And among the 18 students there are 9 students whose grade average is below 80.

So the percentage of the students who spends 4 hours a week on screen is:

= 9 ÷ 18 × 100%

= 100/2

= 50%

hence 50% students spend less than 4 hours a week on screens.
