Answer: The denominator of a fraction tells you the relative size of the pieces. Therefore, the reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size.

Answer:

We need to have a common denominator in order to subtract different fractions because if we have an example like.

5/2 - 6/8 we cannot do that because the denominator is not alike.

We have to use multiplication to help us here.

2 x 8 = 16 !

So. no we have 5/16

so now we do 5 x 8 = 40

So now my new fraction is - 40/16 BUTTTT 40/16 is an improper fraction. so 40/16 = 5/2

Now we are back at the square 1 so now we have to fix 6/8.

8 x 6 = 48

6 x 6 = 36.

--

2 x 24 = 48.

5 x 24 = 120 or 12

now we have 12/48 and  36/48.

We can subtract now!

Hope this helped for problems like this.

Answer:

XV = 4.75

Step-by-step explanation:

TV/WV = UV/XV (similarity theorem)

TW = 9

WV = 3

UV = 19

TV = 9 + 3 = 12

XV = ?

Plug in the values

12/3 = 19/XV

4 = 19/XV

XV × 4 = 19

XV = 19/4

XV = 4.75

Answer:

Assuming the problem asks to rotate counterclockwise: E' (0,0) F' (0,5) G' (-4,5) H' (-4,0)

If it says rotate clockwise then your points will be: E' (0,0) F' (0,-5) G' (4,-5) H' (4,0)

Step-by-step explanation:

Translate the points first by subtracting 3 from the x-coordinates of each, then subtracting 3 from the y-coordinates of each. Next, to rotate them counterclockwise about the origin 90 degrees, switch the x and y coordinates and the sign of the resulting x-coordinate. To rotate clockwise 90 degrees switch the x and y still but change the sign of the resulting y coordinate.

What is the area in square units of triangle QRS also show work
GuDViN [60]
Find the area of the larger rectangle. 
5 x 4 = 20  
One of the triangles is 2 x 2. Area of 2. Subtract 2 from 20.
20 - 2 = 18 
Another is 2 x 5. Area of 5. Subtract 5 from 18. 
18 - 5 = 13 
The last is 3 x 4. Area of 6. Subtract 6 from 13. 
13 - 6 = 7 
The area of the triangle QRS is A, 7. 
Hope this helps!
