Well to find the mean you need to add up the total number of people and then divide by the total number of days meaning if there is a total of 105 people, you would divide that by 5 and get 21
13 + 23 + 24 + 31 + 14 = 105
105 / 5 = 21
Writing the problem as an equation you have:
2x+6 > -16
Solve for x:
2x+6 > -16
Subtract 6 from each side:
2x > -22
Divide both sides by 2:
x > -11
The answer is: x > -11
Here, we can either factor:
1. The numbers
2. The variables
3. Both 1 and 2
In this instance, we factor 1 because the variables are different but the three numbers have a Greatest Common Factor.
4a+12b-20
4(a+3b-5)
Answer:
75min or 1 hour 15min
Step-by-step explanation:
45/12 = 3.75min per problem
3.75 x 20 = 75min or 1 hour 15min
