A constant is simply a number, something that does not change: here it's "2"
A variable can chage: here it's "x" - anything can be substituted for x
If we put those two together with a "+" sign, we get an expression: variables or contants (including multipled ones: such as 2x, which is a term) added to each other or subtracted from each other

Girls are g
b + g = 120
2g = b
Substitute the second equation into the first
2g + g = 120
3g = 120
g = 40
Plug in g = 40 and solve for b
b + g = 40
b + 40 = 120
b = 80
There are 40 girls and 80 boys.

The measure of angle O is 21 degrees.
What are the properties of Triangle?
The properties of the triangle are:
1. The sum of all the angles of a triangle (of all types) is equal to 180°.
2. The sum of the length of the two sides of a triangle is greater than the length of the third side.
3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
The sum of the interior angles in a triangle is 180 degrees. Therefore, we can find the measure of angle O by subtracting the measures of angles N and P from 180 degrees:
m∠O = 180° - m∠N - m∠P
We are given that m∠N = 137 degrees and m∠P = 22 degrees, so substituting these values, we get:
m∠O = 180° - 137° - 22°
m∠O = 21°
Therefore, the measure of angle O is 21 degrees.

Complete question:
in a triangle npo If m∠n = 137 and m∠P = 22, what is m∠O?
- in this case m<O = 180 -(137+22) = 180 -159 = 21
m<O = 21 degrees
