80 people attended a meeting. There was x men and x women and the rest were children. How many children attended the meeting

80 - 2x

Step-by-step explanation:

Given

Total number of people = 80 people

Total men = x men

Total women = x women

Let the number of childeren be c

x + x + c = 80

Make c the subject of the formula

c = 80 - (x+x)

c = 80 - 2x

Hence the total children attending is 80 - 2x

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.
