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,
<h3>What is average?</h3>
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.

I don’t know if I’m seeing the whole problem but what I can say is
x = < 3 because it’s vertical.
x = < 4 because it’s corresponding angles.
x = < 7 because it’s Alt. Exterior
Answer:
25 minutes
Step-by-step explanation:
When there are to people washing one elephant they will take half the time.
So half of the longest time will be the answer to the question.
Mary takes longer then Nigel so once Nigel is finished Mary will still wash her side for 5 minutes extra.
they have to have the same absolute value and one is negative and the other is positive
