So we are given the expression:
÷
When we divide fractions, we must flip the second term and change the sign to multiplication:
And then we multiply across:
Then we can break apart all of the like variables for simplification:
When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:
So then we multiply all of these simplified parts together:
So now we know that the simplified form of the initial expression is: .
Answer:
x=2
Step-by-step explanation:
5x+ = 7
5x+4 =7 (2)
5x+4=14
5x=14-4
5x=10
=
x=2
Hi, Laura! ;)
<h2>The answer to the first question is 5,62.</h2><h2><em>Here is the step by step solution</em>: </h2>They want to know the center of a distribution. Another word for center is middle. When you have a set of numbers, you can find the middle by calculating the mean, the "average" of the data set.
1) Add all the numbers: 12,8 + 5,7 + 7,9 + 1,3 + 3,2 + 2,8 = 33,7
2) Divide the sum by the quantity of numbers, which is 6: 33,7 / 6 = 5,616
The closest number to 5,616 is 5,62.
==========================================================
Now let's answer your second question.
<h2>The correct answer is, indeed, 0,14.</h2><h2><em>How do we get to this number? Here is the step by step solution:</em></h2>1) First step is to find out how many possible outcomes you have. It is the
number of raffle tickets in the box: 200.
2) Then, let's define the number of tickets that are prizes: 4 + 8 + 16 = 28.
The probability of selecting a prize ticket is the number of prize tickets divided by all the raffle tickets in the box: 28 / 200 = 0,14.
Now, let's practice Probability with another Brainly problem:
Good luck, Laura! :)
