Answer:
Step-by-step explanation:
Out of a total of 1, 
went to the fair and 
OF THOSE, bought atleast one book.
To find the fraction of students who bought at least one book, we will multiply both the fractions. That is the answer. Shown below:
Answer is
Answer:
Bill: 8 years
Hoang: 13 years
Step-by-step explanation:
Let's say Hoang has been a nurse for H years and Bill has been a nurse for B years.
Hoang has been a nurse for 5 years longer than Bill. This means that B + 5 = H
Next, 3 years ago, she had been there twice as long.
(B-3) and (H-3) represent Bill and Hoang 3 years ago respectively.
(B-3) * 2 = (H-3)
We thus have two equations
B+5 = H
(B-3) * 2 = H-3
Substitute B+5 for H in the second equation
2*B - 6 = B+5-3
2B-6 = B+2
add 6 to both sides to put all the constants on one side
2B = B + 8
subtract B from both sides to isolate the variable
B = 8
H = B+5 = 13
we know that
Vertical angles are congruent angles
that means
substitute the given values
(7x – 27)=(3x + 29)
solve for x
7x-3x=29+27
4x=56
x=14
part b)
We know that
Supplementary angles are angles that their sum is equal to 180 degrees
so
A+B=180
substitute the given values
5x+25+x+17=180
solve for x
6x+42=180
6x=180-42
6x=138
x=23
Find the measure of Angle A
