9/5-1/5=8/5answer
3.3/2-1/2=2/2answer
Answer:
first question= 7/8
second question= 8/5
third question= 1
fourth question=23/8
fifth question=9/8
final question= 1/3
Step-by-step explanation:
1) 15/8 - 5/8 = 7/8
since the denominator is the same, it will be easier
do 15-8
which is 7
so the final answer is 7/8
(Remember that you don't subtract the denominator)
2) 9/5 - 1/5 = 8/5
Using the same method as the first question, you should get 8/5
8/5 as a mixed fraction would be 1 3/5
3) 1 1/2 - 1/2= 1
1 1/2 into a mixed fraction = 3/2
3/2-1/2
=2/2, which is 1
4) 3 1/4 - 3/8=23/8
3 1/4 as a mixed fraction is 13/4
so the equation would be 13/4 - 3/8
however, the denominator is not the same
and the least common multiple is 8
so 13/4 = 26/8
26/8-3/8= 23/8
5) 5/4 - 1/8 = 9/8
5/4 doesn't have the same denominator as 1/8, so you change it into 10/8
10/8-1/8
9/8
6) final question :)
5/6 - 1/2= 1/3
1/2 = 3/6
5/6-3/6

[tex]2. \ \displaystyle Slope \ of \ \overline{AB} = \mathbf{\frac{7- 1}{3 - (-6)}} = \frac{6}{9} =\frac{2}{3}[/tex]
[tex]\geq \displaystyle Slope \ of \ \overline{CD} = \frac{-5 - (-1)}{-6 - 0} = \frac{-4}{-6}=\frac{2}{3}[/tex]

Directions: To determine if the equations are parallel or perpendicular
Solution:
The equations are parallel if when expressed in the form, y = m·x + c, the value of m are equal
The equations are perpendicular, when we have;
[tex]\displaystyle The \ value \ of \ \mathbf{m} \ in \ one \ equation = -\frac{1}{The \ value \ of \ \mathbf{m} \ in \ the \ other\ equation }[/tex]
7. First equation
3·x + 2·y = 6
Therefore; [tex]\displaystyle y = -\frac{3}{2} \cdot x + 3[/tex]
Second equation; [tex]\displaystyle y = \mathbf{-\frac{3}{2} \cdot x + 5}[/tex]
The value of m which is the coefficient of x are both equal to [tex]\displaystyle -\frac{3}{2}[/tex]
Therefore, the equations are parallel
8. Equation 1; 3·y = 4·x + 15
Therefore;
[tex]\displaystyle y = \frac{4}{3} \cdot x + 5[/tex]
Equation 2; 9·x + 12·y = 12
[tex]\displaystyle y = -\frac{9}{12} \cdot x + 1 = 1 - \frac{3}{4} \cdot x[/tex]
The slope of the equation 2 is the negative inverse of the slope of equation 1, therefore, the equations are perpendicular
9. Equation 1: 8·x - 2·y = 4
Therefore;
y = 4·x - 2
Equation 2: x + 4·y = -12
Therefore;
[tex]\displaystyle y = -\frac{1}{4} \cdot x - 3[/tex]
The slope of the equation 2 is the negative inverse of the slope of equation 1, therefore, the equations are perpendicular.
10. Equation 1: 3·x + 2·y = 10
Therefore;
[tex]\displaystyle y = -\frac{3}{2} \cdot x - 5[/tex]
Equation 2: 2·x + 3·y = -3
[tex]\displaystyle y = -\frac{2}{3} \cdot x -1[/tex]
The slopes of the equation 1 and 2 are not equal, and are not the negative inverse of each other, therefore, the equations are neither parallel nor perpendicular.

Carrie, Maria, and Nayla are friends that live close to one another. Which two friends have the shortest distance between them?
a-Carrie and Maria
b-Maria and Nayla
c-Carrie and Nayla
d-All three live equal distances from each other.
Answers
The two friends have the shortest distance between them are Carrie and Nayla.
In order to determine the distance of the friends from each other, the value of the angles have to be determined. The given figure is a triangle. Sum of angles in the triangle equal 180 degrees.
The first step is to determine the value of x:
20x + 7) + (5x + 50) + (5x + 3) = 180
Add similar terms togethers
30x + 60 = 180
Combine similar terms
30x = 180 - 60
30x = 120
x = 120 / 30
x = 4
The second step is to determine the value of each angle
Nayla = 20(4) + 7 = 87
Carrie = Second angle = 5(4) + 50 = 70
Maria = Third angle = 180 - (70 + 87) = 23
Nayla and Carrie live closest to each other
