Solution:
Note that:
Given equation: -8(5 - 3n + 7n) = -40 + 24n - 56nSimplify both sides:
-8(5 - 3n + 7n) = -40 + 24n - 56n=> -40 + 24n - 56n = -40 + 24n - 56nSince both sides are equal, this equation has infinite solutions.

Sum of two odd numbers will always be even.
Sum of two even numbers will always be even.
Sum of one odd and one even number will always be odd.
Let the both numbers be first and second.
According to the problem statement:
first + second = 19
first – second = 5
Add both equations:
first + second + first – second = 19 + 5
2 * first = 24
first = 24 / 2
first = 12
So from this we get first = 12, put this value in any equation i.e.
first + second = 19 (Put the value of first in this equation)
12+ second = 19
second = 19 – 12
second = 7
So, the numbers are 12 and 7.
The sum of three consecutive even numbers is one hundred sixty-two. what is the smallest of the three numbers?
please show work and answer.
Answer:
54
Step-by-step explanation:
The numbers are 54, 56 and 58 because 54 + 56 = 110 and 58 + 110 = 168. So lead to 54 being the smallest of the three.

Classify each pair of numbered angles as corresponding, alternate interior, alternate exterior, or none of these.
Drag and drop the choices into the boxes to correctly complete the table.
corresponding alternate interior alternate exterior none of these
Alternate exterior angle - 2nd
corresponding angle - 5th and 3rd
vertical angle - 1st
Alternate interior angle - 4th
1st angles goes to none of these box because vertical angles are not asked.

Answer:
68% 32%
73.5% 26.5%
Step-by-step explanation:
Start:
total number = 561 + 264 = 825
glucose aversion = 561
percent = 561/825 × 100% = 68%
no glucose aversion: 264
percent = 264/825 × 100% = 32%
End:
total number = 441 + 159 = 600
glucose aversion = 441
percent = 441/600 × 100% = 73.5%
no glucose aversion: 159
percent = 159/600 × 100% = 26.5%
The Taft Public Library is a library built in the shape of a square. The checkout desk is located in the center of the building. You have been asked to help make a map of the library, using a coordinate plane. Since the library is 100 feet on each edge, you have decided to use a coordinate plane from -10 to 10 on each axis. Each unit represents 5 feet. The y-axis runs north-south, and the x-axis runs east-west.

What are the measures of ∠ADC and ∠DCB in the figure?
Answer:
measure of angle ADC = 100°
measure of angle DCB = 39°
Step-by-step explanation:
We know that all the interior angles of a triangle add up to equal 180°, so we can set up an equation based on what we know from the figure (Angle C is the sum of [tex](4x-1)[/tex]° and [tex](2x+17)[/tex]°):
180° = 43° + 61° + [[tex](4x-1)[/tex]° + [tex](2x+17)[/tex]°]
180° = 43° + 61° + [tex]6x +16[/tex]°
180° = 104° + 16° + [tex]6x[/tex]
180° = 120° + [tex]6x[/tex]
60° = [tex]6x[/tex]
10° = [tex]x[/tex]
Now that we know the value of [tex]x[/tex], we can easily plug in 10° for [tex]x[/tex] in the angles we need to find.
The second angle we need to find uses [tex]x[/tex], so we can now find it. Angle DCB is, according to the figure, equal to [tex]4x-1[/tex].
[tex]4x-1[/tex]
[tex]4(10)-1\\40-1\\39[/tex]
Thus, the measure of angle DCB is equal to 39°.
However, angle ADC is defined in terms of [tex]y[/tex], so we'll have to find the value of [tex]y[/tex]. This is easy, however, because the two angles using [tex]y[/tex] meet together to form a straight line. Since we know that a straight line has an angle measure of 180°, we can once again set our equation equal to 180°.
180° = [tex](3y+7)+(3y-13)[/tex]
180° = [tex]6y[/tex] + 7° - 13°
180° = [tex]6y[/tex] - 6°
186° = [tex]6y[/tex]
31° = [tex]y[/tex]
Now, we'll simply substitute 31° for [tex]y[/tex] in the measure of angle ADC:
[tex]3y+7\\3(31)+7\\93+7\\100[/tex]
Therefore, the measure of angle ADC is equal to 100°.
The measure of <ADC is 100 Degree and measure of <DCB is 39 Degree.
What is Angle Sum Property?The angle sum property of a triangle states that the sum of the angles of a triangle is equal to 180º.
Given:
First, (3y+ 7) + (3y - 13) = 180 (Linear Pair)
6y - 6 = 180
6y = 186
y = 31
So, measure of <ADC = 3y+ 7 = 3(31)+ 7 = 93 + 7 = 100 Degree
In Triangle ADC, using Angle Sum property
3y -13 + 61 + 4x - 1 = 180
93 - 13 + 61 - 1 + 4x = 180
4x = 40
x= 10
So, the measure of <DCB = 4x-1 = 4(10)-1 = 39 Degree.

For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.

A student attempted to generate an equivalent expression using the distributive property, as shown below: 5(x − 1) = 5x − 1 What was the mistake made? (1 point) 5 was not multiplied by x Incorrect sign was used for the first term 5 was not multiplied by −1 Incorrect sign was used for the second term
Answer:
the correct answer must be 5x - 5 not 5x - 1
Step-by-step explanation:
when we have a question such as 5(x - 1)
we must multiply both the numbers by 5
so we get 5 X x and 5 X -1
so it will be 5x - 5 which is the answer.
