Question

5. At a classroom costume party,

Answer 1

Answer:

42+b+g

Step-by-step explanation:

42+b+g is the only specific answer because b (boys) and g (girls) are not specified as numbers.

Answer 2

The required simplified value of b + g is 21.

Given that,

At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

Here,

The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,

Now,
average of  n = 3 (b , g , b+g)
Average =  g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g +  42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21

Thus, the required simplified value of b + g is 21.
