Answer:
65
Step-by-step explanation:
the angle on top is the same because the lengths of the lines that meet to "H" are the same.
The average number of hours can be calculated using the following rule:
average number of hours = total number of hours / total number of weeks
total number of hours = 36 3/8 + 41 1/4 + 40 1/2 + 38 3/8 = 313/2 hours
total number of weeks = 4 weeks
Average number of hours per week = (313/2) / (4) = 39 1/8 hour
Based on the above calculations, the correct answer is:
C. 39 1/8 hour
Answer:
36 %
Step-by-step explanation:
9 girls = 36%
25 students = 100
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
Let's represent the two integers with the variables 
and 
.
From the problem statement, we can create the following two equations:
With the first equation, we can subtract from both sides to isolate the variable to the left-hand side:
Now that we have a value for , we can plug it into the second equation and solve for :
Now, let's move everything to one side of the equation:
Factoring this quadratic will give us two values for :
Since we now know , we can plug this back into either of the original equations to get a value for , which will be 
.
So the two numbers that sum to 
and have a product of 
are 
.
