X + x + x + x = 28
Solve for X
Steps to solve:
X + x + x + x = 28
~Combine like terms
4x = 28
~Divide 4 to both sides
x = 7
Best of Luck!
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
[tex]x+x+x+x=28[/tex]
Add the "x" variables together:
[tex]4x=28[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4}=\frac{28}{4}[/tex]
[tex]x=7[/tex]
Simplify
1/4 + 4(1/2 - 3/4)^2
How can you tell Is something is a unit rate
Unit rate is a ratio between two different units with a denominator of one. When we divide a fraction's numerator by its denominator, the result is a value in decimal form. For example: 8/4 = 2 and 3/6 = 0.5. When we write numbers in decimal form, we can write them as a ratio with one as the denominator.
For example, we can write 2 as 2/1, and 0.5 as 0.5/1. However, since that approach can be a little clumsy, we usually drop the one. That said, it's important to remember the one is there, especially when working with unit rates.
For instance, 8 miles/4 hours = 2 miles/hour. Notice again that, while we did not include the 1, we did include the unit 'hour' Miles per hour is a familiar expression, as are unit rates such as:
interest/amount invested
revolutions/minute
salary/year
Conversationally, the word ''per'' indicates we are using a unit rate.

What is the equation of a line that contains point (4, –3) and is PARALLEL to –4x + y = 7?
Answer:
(4,3),y=(7)/(4)x+1
Step-by-step explanation:
To find an equation that is parallel to y = 7 4 x + 1 y=74x+1, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula. ( 4 , 3 ) (4,3) m = 7 4
Using the point-slope form y − y 1 = m ( x − x 1 ) y-y1=m(x-x1), plug in m = 7 4 m=74, x 1 = 4 x1=4, and y 1 = 3 y1=3. y − ( 3 ) = ( 7 4 ) ( x − ( 4 ) )
Solving for y:
Multiply − 1 -1 by 3 3. y − 3 = ( 7 4 ) ( x − ( 4 ) ) y-3=(74)(x-(4)) Simplify ( 7 4 ) ( x − ( 4 ) ) (74)(x-(4)).
y − 3 = 7 x 4 − 7
y = 7 x 4 − 4 y=7x4-4 Reorder terms. y = 7 4 x − 4

Answer: Choice D
(a-e)/f
=======================================
Explanation:
Points D and B are at locations (e,f) and (a,0) respectively.
Find the slope of line DB to get
m = (y2-y1)/(x2-x1)
m = (0-f)/(a-e)
m = -f/(a-e)
This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.
Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.

Arguments:
A There is a need for students to understand and be able to construct geometric figures using a compass and straightedge.
B There is no need for students to use a compass and straightedge, and all geometric constructions should be done using a drawing program.
What needs to be done:
A summary of your argument. The summary should begin with the argument statement you chose.
In addition, provide at least three reasons why the method you chose is better than the other method and at least three reasons why the other method is not better.
A list of at least two resources used. Resources may include interviews with professionals and/or URLs of websites
Three reasons why the other method is not better is because to use drawing program would mean you would need some sort of technology and electricity to use it and some places, like third world countries, do not have access to that, so most probably you would have to resort to paper. Also, drawing programs are based off the skills needed to create geometric figures with a straightedge and compass. And lastly, what if we had no more technology anymore? Then how would we use a drawing program? Drawing programs are only reliable when electricity is located.
SO THE ANSWER IS A hope it help :)
I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.
The compass and straightedge can be used anywhere. The compass and straight edge have been around for lots of years. They are a valuable tool for students in math and in real world applications. The compass and straightedge are portable and handy to use any given time. That is why there is a need for students to understand and be able to construct geometric figures using a compass and straight edge.
The compass and straight edge have been used to accurately create geometric figures for thousands of years. This shows that they are accurate and useful to us. Using technology is less reliable for many reasons. Technology can break, or glitch and shut down, making you lose all your work. You cannot draw on physical objects with an iPad like you could with a pencil or pen. Having a physical copy of things makes things easier to keep track of. Having a blueprint would be better than having a drawing on your phone. You can get another blueprint, but if your phone breaks and that drawing isn't saved, it's gone.
These are only a few reasons why I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.
How do you know which function is the inner radius and which is the outer radius?
Step-by-step explanation:
Graphing them is the best way to tell (I put one from Desmos in th attachment scribbled on it a little to match our situation). Otherwise you'll just have to know which one is going to be where on the interval given; but that knowledge comes by graphing them a lot anyways.
Also remember to draw your strips/lines from the axis of revolution to the curves. The longer one will represent the outer radius of the volume and the shorter one the inner radius.
So:
Graph the functions.Draw your strips/linesOuter is longer, Inner is shorterComment with any questions.
What is 115% of 4? Round to the nearest hundredth
Answer:
4.6
Step-by-step explanation:
Answer:
4.6
Step-by-step explanation:
1. We assume, that the number 4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 4 is 100%, so we can write it down as 4=100%.
4. We know, that x is 115% of the output value, so we can write it down as x=115%.
5. Now we have two simple equations:
1) 4=100%
2) x=115%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
4/x=100%/115%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 115% of 4
4/x=100/115
(4/x)*x=(100/115)*x - we multiply both sides of the equation by x
4=0.8695652173913*x - we divide both sides of the equation by (0.8695652173913) to get x
4/0.8695652173913=x
4.6=x
x=4.6
now we have:
115% of 4=4.6

Solve: (y) (12y – 5) = 0.
I’m not sure if my answer is correct
Answer: y = 0, 5/12
Step-by-step explanation:
(y)(12y-5) = 0
12y^2 - 5y = 0
After factoring:
y(12y - 5) = 0
Therefore,
y = 0 OR y = 5/12
