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.

The value of c in the parallelogram is 45
<h3>How to determine the value of c?</h3>
From the question, we have the following parameters:
- Parallelogram PARL is similar to parallelogram WXYZ.
- AP = 15, PL = 25, and WZ= 75
To calculate the value of c, we make use of the following equivalent ratio.
AP : PL = XW : WZ
Substitute the known values in the above equation
15 : 25 = c : 75
Express the above equivalent ratio as fractions
15/25 = c/75
Multiply both sides of the equation by 75
75 * 15/25 = c/75 * 75
Evaluate the product
75 * 15/25 = c
Evaluate the product
1125/25 = c
Evaluate the quotient
45 = c
Rewrite the equation as
c = 45
Hence, the value of c in the parallelogram is 45
