Answer:

x = 4

Step-by-step explanation:

\frac{7 + 2x}{3} = 5

Multiply both sides of the equation by 3

7 + 2x = 15

Subtract 7 from both sides of the equation

2x = 8

Divide both sides of the equation by 2

x = 4

This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old.

A

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

5c

Now lets take out the numbers:
