How do you solve multi step equations (ik how to do) but with the variables and doing distributive property? I know to start you distribute parenthesis but after that I kinda get lost. Explain it by using an example equation and go deep into explanation and you will totally get brainiest!!
Answer:
Let's say we have this equation, for example⤵⤵⤵:
[tex]12 - 6(x + 10) = 60[/tex]
You obviously know that first you must distribute -6 amongst everything inside the parenthesis, and that will give you -6x - 60. Then you'd rewrite the equation with this in mind, to get
12 - 6x - 60 = 60
Next, you need to combine the like terms, in this case 12 and -60, to get -48. Now you have
-6x - 48 = 60
Afterwards, you'd do the opposite of -48 and add it on both sides of the equal sign. Now you'll have -6x = 108
Finally, you'd divide -6 on both sides, in order to get x by itself, to get x = -18
Hopefully, this example/explanation helps you understand the concept better :)

Find the value or expression for 0.
1. sin(55) = cos( )
2. sin ( ) = cos(28)
3. cos(y) = sin( )
Using complementary angles, it is found that the values for the expressions are given as follows:
1. sin(55) = cos(35).
2. sin (62) = cos(28).
3. cos(y) = sin(90 - y).
What are complementary angles?
Two angles are called complementary if the sum of their measures is of 90º; If two angles are complementary, the sine of one is the cosine of the other.
Hence, since 55 + 35 = 62 + 28 = 90, we have that the values are given as follows:
1. sin(55) = cos(35).
2. sin (62) = cos(28).
3. cos(y) = sin(90 - y).

Is the sky blue???????
No No the sky is not blue.
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
To understand why the sky is blue you need to remember how color works. Color is largely caused by how well an object absorbs the light spectrum. When you see a blue sky you only see blue because all the other colors were absorbed in the air. Any object with color works that way. For example a red ball is read because all the colors of light are absorbed by the ball except for red. This reflected light is what gives the object color.
This is what happens with the sky. The atmosphere is denser than we imagine and the different gases give the atmosphere unique properties in how it absorbs, diffuses, and reflects light. When sunlight passes through our atmosphere a portion of it is scattered and absorbed. The remainder either reaches the surface or is reflected back. The portion that makes it to us observers is 75 percent.
This process is called diffused sky radiation. So to review, we color because objects due to texture of dyes and surfaces absorb all light wavelengths and reflect back one or more. The reason we see the sky as blue is because the molecules in the air scatter the light absorbing most wavelengths of light except for blue.
In addition to this the sky is gray and overcast because of the water droplets in the atmosphere in the forms of clouds and humidity. water refracts light equally unlike air molecules in the atmosphere. This means we get the entirety of white light only it is dimmer just like when you shine a light through a white sheet.
The fact we see a blue sky is good thing because its shows that are atmosphere is at work shielding us from the full energy of the sun’s rays. While the sun is the largest source of energy to our planet, a lot of its high energy radiation that is deadly for living things. Our atmosphere plays it part by shielding us from that. So when you see a blue sky with your kid you can tell them it means the sky is acting like a huge shade blocking out the bad parts of the sun.

SOMONE EXPLAIN CALCULUS TO MEEEE
Answer:
Calculus is when you make that amount of time tinier and tinier and tinier, and that makes the distance tinier and tinier and tinier too, so that, at that moment, the tiny distance divided by the tiny time is 31 miles per hour, but a second later it might be 30 mph or 32 mph or something else.
Step-by-step explanation:
Calculus is a branch of mathematics that involves the study of rates of change. ... Calculus helped to determine how particles, stars, and matter actually move and change in real time. Calculus is used in a multitude of fields that you wouldn't ordinarily think would make use of its concepts.
Categories
It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while integral calculus concerns accumulation of quantities, and areas under or between curves.

The roots of the quadratic function describing the relationship between number of
products produced and overall profit margin are x = 0 and 28. The vertex is a minimum
at (14, -40)
The company actually loses money on their first few products as it costs them more to
make them, but once they hit items they break even again.
The worst case scenario is that they produce items, as they will have a profit of
dollars. The first root tells us that the profit will be 0 when products are
sold.

Answer:
? = 13
Step-by-step explanation:
40.5/9 = 4.5
9 x 4.5 = 40.5
X x 4.5 = 58.5
4.5X = 58.5
4.5X/4.5 = 58.5/4.5
x = 13
Answer:
13
Step-by-step explanation:
We are given the sides of one of the triangles. If you take 9/40.5, you get .2222222. We can then use that to find the base. If you take 58.5, multiply it by .22222, you get 13!
The percent change from 45 to 90 is
A change from 45 to 90 represents a positive change (increase) of 100%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old|Old| × 100%
Percent change = 90 - 45|45| × 100% =
4545 × 100 = 100% (increase)
Where: 45 is the old value and 90 is the new value. In this case we have a positive change (increase) of 100 percent because the new value is greater than the old value.
The number of students in a school is between 500 and 600. If we group them into groups of 12, 20, or 36 each, 7 students are always left over. How many students are in this school?
There are 547 students in this school.
How did we arrive at the value?Let's solve this problem step by step.
1. We know that the number of students is between 500 and 600 and leaves a remainder of 7 when divided by 12, 20, or 36.
2. To find the number of students, we need to find a number that satisfies all these conditions.
3. Let's start by finding the least common multiple (LCM) of 12, 20, and 36, which is 180.
4. Now, we can represent the number of students as 180n + 7, where n is a positive integer.
5. To find a value of n that falls within the range of 500 to 600, we can try different values for n until we get a suitable number.
Let's calculate:
For n = 3: 180 * 3 + 7 = 547 (Within the range)
For n = 4: 180 * 4 + 7 = 727 (Exceeds the range)
So, there are 547 students in this school.

Round the following numbers to the nearest 100. 468 1350 6849
The solution is, rounding off the numbers to the nearest 100. 468 1350 6849, is: 500, 1300, 6800.
What is round off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
here, we have,
given that,
the numbers are 468, 1350, 6849
now, we have to Round the following numbers to the nearest 100.
To round a number to the nearest 100, look at the tens digit. If the tens digit is 5 or more, round up. If the tens digit is 4 or less, round down.
so, we get,
468 => 6>5, so, 468 =>500
1350 => 35 < 50, so 1350 => 1300
6849 => 4<5 , so , 6849=> 6800
Hence, The solution is, rounding off the numbers to the nearest 100. 468 1350 6849, is: 500, 1300, 6800.
