Answer:
1. 5x +43
2. -1.5x - 7
3. 6.2 - 2x
Step-by-step explanation:
Equation 1:
5 (x+8) +3
First, we can distribute the 5 to the (x+8) and get 5x + 40. Distributing is when we multiply the 5 by the first number (x) and then by the second number (8) Because they aren't like terms (don't both have x's) we cannot combine then and must keep them separated by a subtraction sign
Now we have: 5x + 40 + 3
Next, we can combine the like terms. This means that any that have the same variable can be combined. So, the 5x has no other x's so he has to stay how he is. The 40 and the 3, however, can be added together to get 43.
Our finished equation is: 5x + 43
Equation 2:
3.6x - 7 - 5.1x
First, we can combine like terms as we learned in the last problem. This would be our x's since we have multiple.
We can add 3.6x and -5.1x and get -1.5x
Now we have: -1.5x - 7
Equation 3:
4 + 8x + 2.2 - 10x
We can start with either the numbers with x's or without but I'll just do the x's. So we have 8x and -10x. Adding these together would get us -2x.
Next, we can combine 4 and 2.2 and get 6.2.
Now, putting these back into our equation would look like this:
6.2 - 2x

A=2πrh+2B solve for b
Answer:
b = [tex]\frac{A-2\pi rh}{2}[/tex]
Step-by-step explanation:
Given
A = 2πrh + 2b ( subtract 2πrh from both sides )
A - 2πrh = 2b ( divide both sides by 2 )
[tex]\frac{A-2\pi rh}{2}[/tex] = b

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line.
a
(4, 3), (2, 2)
Answer:
The slope is 1/2
Step-by-step explanation:
Answer: 0.5
Step-by-step explanation:
The equation for finding a slope is y2 - y1/x2 - x1
so 2 - 3 = -1
and 2 - 4 = -2
so -1/-2 whish is 0.5
A man sold two computers for Rs. 24,000 each. On one
he gained 20% and on the other, he lost 20%. Find his gain
or loss percentage of his whole transaction.
Answered
Sale price of first computer = Rs 24000
gain = 20%
So cost of first computer = 100/120 x 24000 = Rs 20,000
Sale price of second computer = Rs 24000
Loss 20%
So cost of second computer = 100/80 x 24000 = Rs 30,000
Total cost = Rs 50,000
Total sale value = Rs 48000
Loss = Rs 2000
Loss % = 2000/50000 x100= 4 % LOSS ANSWER

The yearbook club has 5 members returning from last year. They set up a booth in the cafeteria to recruit more members, and an average of 3 new members sign up each day. Which best describes why the graph relating the total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be continuous or discrete?
The graph will be continuous because an end day for the booth being set up is not given in the description.
The graph will be continuous because there can be any number of people signing up each day since we are only given the average.
The graph will be discrete because some day the number of available people to sign up for the club will run out.
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
The correct option is the graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
What is Discrete Random Variable?Discrete random variables are defined as the variable which takes only finite number of distinct values in the data set.
These variables are usually countable.
Continuous random variables are those which take infinitely many values in the data set.
These include all set of real numbers.
Here the situation is the recruitment of members for the yearbook club.
The members coming for sign up will only in the form of numbers like 0, 1, 2, 3, ........
There is nothing like partial person coming for the sign up.
And there will be only finite number of members each day because booth is set up only once in each day.
Hence the graph of total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be discrete.

What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The distance between two coordinates (x₁,y₁) and (x₂,y₂) are given by
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
So,
d = [tex]d = \sqrt {\left( {-1 - 4 } \right)^2 + \left( {3 - 0 } \right)^2 }[/tex]
d = [tex]\sqrt{34}[/tex]
d = 5.83 units.
Hence "The value of MN for the given graph will be 5.83 units".

Answer:
[tex]n=\frac{189}{104}[/tex]
Step-by-step explanation:
7−2(8n−3)=4(n−2)(22)
Step 1: Simplify both sides of the equation.
7−2(8n−3)=4(n−2)(22)
7+(−2)(8n)+(−2)(−3)=88n+−176(Distribute)
7+−16n+6=88n+−176
(−16n)+(7+6)=88n−176(Combine Like Terms)
−16n+13=88n−176
−16n+13=88n−176
Step 2: Subtract 88n from both sides.
−16n+13−88n=88n−176−88n
−104n+13=−176
Step 3: Subtract 13 from both sides.
−104n+13−13=−176−13
−104n=−189
Step 4: Divide both sides by -104.
