Give a example of a multi-step equation for each of the following solution

Mathematics

ikadub [295]3 years ago
3 0

Here is the example.

Multi-step equation means before start solving equations, you need to isolate the variable terms and constant terms, then you have to combine the like terms.

Finally, you can solve the equation. This involves more than two steps.


Examples:

1) 2x + 3x + 5 = 20

Step 1: Isolate the variable terms and constants.

Subtract 5 on both sides, we get

2x + 3x + 5 - 5 = 20 -5

2x + 3x = 15

Step 2: Combine the like terms.

5x = 15

Step 3: Divide both sides by 5.

5x/5 = 15/5

x = 3.


2) 2(3x + 2) = 3(x - 1) + 4

Step 1: Use the distributive property and expand the given equation.

6x + 4 = 3x -3 + 4

Step 2: Isolate the variable terms and constants

Subtract 3x from both sides, we get

6x - 3x + 4 = 3x - 3x -3 + 4

3x + 4 = -3 + 4

Step 3: Simplify it.

3x + 4 = 1

Step 4: Subtract 4 from both sides.

3x + 4 - 4 = 1 - 4

3x = -3

Step 5: Divide both sides by 3.

3x/3 = -3/3

x = -1.

Hope this will help you. :)

Suppose Johnny invests $2,745 into an account, which has been earning interest for many years and he now has a total of $39,974.
Doss [256]
A negative number in this wouldn't be applicable.
Johnny started out with $2,745 in the beginning, EARNING (This being the key word) interest each year. Therefore, he comes out with $39,974, not being a negative number. 

Hope I helped! ^-^

Give at least one way that terminal-digit and middle-digit numbering are alike and one way that they are different.
belka [17]

Terminal digit filing is a filing system that works by means of the last two numbers on files to consolidate them. While middle digit filling uses a tripartite number, using the first part of the number for the second sort, middle part for the initial sort, and the third portion for the final sort. One way they are similar is that the two evade working with large numbers and overpowers the difficulties of crowding at the end of the storage.

How do you evaluate sin(13π/12)?
Alekssandra [29.7K]

13pi/12 lies between pi and 2pi, which means sin(13pi/12) < 0

Recall the double angle identity,

sin^2(x) = (1 - cos(2x))/2

If we let x = 13pi/12, then

sin(13pi/12) = - sqrt[(1 - cos(13pi/6))/2]

where we took the negative square root because we expect a negative value.

Now, because cosine has a period of 2pi, we have

cos(13pi/6) = cos(2pi + pi/6) = cos(pi/6) = sqrt[3]/2

Then

sin(13pi/12) = - sqrt[(1 - sqrt[3]/2)/2]

sin(13pi/12) = - sqrt[2 - sqrt[3]]/2
