20...3,9
5.....x
----------
20x=5*3,9
20x=19,5
x=19,5:20
x=0,975

You can also do it like this:

20:5=4
3,9:4=0,975

I hope it's correct and it helps you. :)

Which fraction is bigger 2/6 or 2/4
Rina8888 [55]
2/4 is the larger fraction. Think of a candy bar that is cut into 4 equal pieces. Now think of the same sized candy bar cut into 6 pieces. The candy bar that has been cut into sixths has more pieces but they are smaller pieces that the candy bar cut into fourths. **When comparing fractions, if the numerators are the same (like they are in this problem) look at the denominators. Whichever fraction has the greater number is actually going to be the smaller fraction (more pieces, but smaller pieces). If the denominators are the same, then the fraction that has the greater number in the numerator will be the larger fraction (more same-sized pieces than the other fraction) Hope that helps!

Add the equations.<br>2x-3y = -1<br>+ 3x + 3y= 26<br><br>​
hichkok12 [17]

Answer:

The answer in the procedure

Step-by-step explanation:

we have

2x-3y=-1 ----> equation A

3x+3y=26 --> equation B

Solve the system by elimination

Adds equation A and equation B

2x-3y=-1

3x+3y=26

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

2x+3x=-1+26

5x=25

x=25/5

x=5

Find the value of y

substitute the value of x in equation A or equation B and solve for y

2(5)-3y=-1

10-3y=-1

3y=10+1

y=11/3

Find f(-7) when f(x)=- 29/x-4
vladimir1956 [14]

Answer:

f(-)=29/11

Step-by-step explanation:

Even though you don't want an explanation, I'll just tell you the basics lol.

So what you have to do, is plug in -7 for the x's.

it should look something like the equation below.

f\left(-7\right)=\frac{-29}{-7-4}

After that all you need to is just to subtract :)

f\left(-7\right)=\frac{-29}{-11}

Then after that all you need to do is just let the negatives cancel out each other so you should get:

f\left(-7\right)=\frac{29}{11}

Hope this helps!
