Answer:

x = -2/4

Step-by-step explanation:

You always want to leave the variable alone-

-4x + 7 = 9

To do that you need to get rid of the seven and that can be done by subtracting/adding it by its opposite value in both sides of the equation.

-4x = 2

Get rid of that 4 by dividing from both sides of the equation-

x = -2/4

Answer:

x= -1/2

Step-by-step explanation:

Mkay... You would start off by getting rid of the parentheses because they aren't needed here...

7 - 4x = 9

Now, you would add 4x to both sides to get rid of the subtraction...

7 = 9 + 4x

Then, you subtract 7 from each side....

0 = 2 + 4x

Moving on, you would subtract 2 from each side...

-2 = 4x

And then divide 4 on each side to get...

x = -1/2

And there's your answer!

Answer:

The answer to number one is 3 1/2, the answer to number two is 3 1/3, the answer to number three is 1 1/4, the answer to number four is 1 3/5, the answer to number five is 3 1/5, the answer to number six is 19/4, the answer to number seven is 27/5, the answer to number eight is 35/3, the answer to number nine is 24/7, and the answer to number ten is 13/6.

Step-by-step explanation:

To change an improper fraction into a mixed number, you hate to divide the numerator by the denominator. For example, if the improper fraction was 10/5, you would get 2 because 5 goes into 10 two times. If the improper fraction was 8/5, you would do the same thing and get 1 3/5 because 5 goes into 8 once, and since 8 minus 5 is 3, you get 3 over 5.

To change a mixed number into an improper fraction, you have to multiply the denominator my the whole number, and then take that number and add it by the numerator. For example, if the mixed number was 8 2/3, the improper fraction would be 26/3 because 3 times 8 is 24, and 24 plus 2 is 26.

I hope this helps you have a wonderful day :D

A randomly generated list of numbers from 0 to 4 is being used to simulate
Temka [501]

Answer:

0.6 probability.

Step-by-step explanation:

Probability of an equally likely situation is measured by # of successes/total # of possibilities.

Thus, there are 3 different values of success(2,3,4)

On the other hand, there are 5 possible different values on the list as per the question(0,1,2,3,4).

Therefore, our probability is equal to 3/5 = 0.60 = 60%

Can you answer and explain how to do this?<br><br> 1x-4-3x=2x-3-1
OverLord2011 [107]
Here is what you have to do first, combine like terms. On the left side do x-3x (you can do 1x-3x because x is just 1 variable, so I can see why you put 1x instead of x). Then combine -3-1. Then add the x answer on the left side to the 2x on the other side then you can figure out the rest. The reason why I want you to figure out the rest is because I'm just helping you and you need to get the answer yourself.
