Answer:
20%
Step-by-step explanation:
Total = 45
Absentees = 9
Percentage = (No. of absentees / total) × 100
= 9 / 45 × 100
= 0.2 × 100
= <u>20%</u>
The ordered pair for the other end is (35, 3).
Here, first endpoint = (-15, -3)
Midpoint = (10, 0)
From the midpoint formula, we know that:
M = (x1 + x2)/2 , (y1 + y2)/2
So, here M = (10, 0)
x2 = -15
y2 = -3
We will separate the equation (1), in two parts to get the value of x1 and y1.
(x1 + x2)/2 = 10 and (y1 + y2)/2 = 0
For x1,
(x1 + (-15))/2 = 10
x1 = 35
For y1,
(y1 + (-3))/2 = 0
y1 = 3
So, x1 = 35 and y1 = 3.
Therefore, the ordered pair that represents the other end of the segment is (35, 3).

Answer:
m<ABC = 45
m<DBC = 34°
Step-by-step explanation:
Given:
m<ABD = 79°
m<ABC = (8x - 3)°
m<DBC = (5x + 4)°
Step 1: Generate an equation to find the value of x
m<ABC + m<DBC = m<ABD (angle addition postulate)
(8x - 3) + (5x + 4) = 79
Solve for x
8x - 3 + 5x + 4 = 79
13x + 1 = 79
Subtract 1 from both sides
13x + 1 - 1 = 79 - 1
13x = 78
Divide both sides by 13
x = 6
Step 2: find m<ABC and m<DBC by plugging the value of x into the expression of each angle
m<ABC = (8x - 3)°
m<ABC = 8(6) - 3 = 48 - 3 = 45°
m<DBC = (5x + 4)°
m<DBC = 5(6) + 4 = 30 + 4 = 34°

Answer:
All of the above
Step-by-step explanation:
The question is asking you which equation you can use for you to find the value of the undefined variable, n.
In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.
6ax is a common factor, so divide top and bottom by 6ax:
(a-3x+7ax)/6ax.
Divide each of the terms in the numerator by the denominator:
1/6x-1/2a+7/6
