Answer:

134/25

Step-by-step explanation:

To change from a mixed number to an improper fraction, we take the denominator and multiply by the whole number. Then we add the numerator. Take the total and put it over the denominator.

5 9/25

We take the denominator and multiply by the whole number.

25*5 = 125

Then we add the numerator.

125+9 = 134

Take the total and put it over the denominator.

134/25

Answer:

This cannot be solved but it can be simplified

first we open the bracket

so we have

a²- abx/x = 2/3

next we cross multiply so it will be 3(a² - abx) = 2x

we get

3a² - 3abx = 2x

Next we factorise so we can get

3a(a-bx) =2x

I dont know what exactly you where asked but I hop this helps

Please help me, I'm doing a test.

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: $\left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.$

next you're going to substitute the given value of -2x into the equation $-2x+3y=6$

so your equation should now be: $2-2y+3y=6$

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation $-2x=2-2$ × $4$

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)

The frequency table shows how many visits to the library students in a school have made in the last month.

<h3>Answer: 2.8</h3>

=======================================================

Explanation:

Multiply each visit count with their corresponding frequency.

Examples:

0*12 = 0 for the first row.
1*366 = 366 for the second row
2*53 = 106 for the third row

and so on...

I recommend making a third column like this

$\begin{array}{|c|c|c|} \cline{1-3}\text{Visits} & \text{Frequency} & \text{Visits*Frequency}\\\cline{1-3}0 & 12 & 0\\\cline{1-3}1 & 366 & 366\\\cline{1-3}2 & 53 & 106\\\cline{1-3}3 & 52 & 156\\\cline{1-3}4 & 155 & 620\\\cline{1-3}5 & 243 & 1215\\\cline{1-3}\end{array}$

That way you can keep track of all the results in an organized way.

Then add everything in the third column

0+366+106+156+620+1215 = 2463

Divide this sum over the total frequency (12+366+53+52+155+243 = 881) and we'll get the mean

2463/881 = 2.7956867

Rounding to one decimal place gets us to 2.8 as the final answer.

-------------

The much longer way to do this is to imagine 12 copies of "0", 366 copies of "1", 53 copies of "2", and so on. We'll have an extremely large data set of 881 items inside it. As you can see, this second method is definitely not recommended to actually carry out. Rather it's helpful to have this as a thought experiment to see why we revert to multiplication instead.

Eg: Imagine adding 155 copies of "4". A shortcut is to simply say 4*155 = 620
