Help with this question I also need explanation on how to do it!

Mathematics

Ad libitum [116K]3 years ago

Answer:

C. It is correct because 1 7/9 x 3/8 equals 2/3

Step-by-step explanation:

- First we need to figure out if the solution is correct or incorrect. To do this, we will flip the fraction and multiply it. For example...

2/3 x 8/3 = 16/9 = 1 7/9

- Now we must determine which of the two correct options is correct. Lets try C.

You need to take 16/9/9 x 3/8 = 2/3. As you can see, this is correct and works.

- Hope this helps! If you would like a further explanation please let me know.

Answer choices:<br>A (3 , -4)<br>B (4 , -7/2)<br>C (-5 , 8)<br>D (5/2 , -17/4)​
zhuklara [117]

Answer: D (5/2, -17/4)

Step-by-step explanation:  Using elimination your goal is to get rid or 1 variable  so you can solve for the one that's left.  By adding the -2y and 2y you will get 0.  You will also add the 3x+x (4x) and -1+11 (10).  You have now gotten rid of the y and have 4x=10.  By dividing each side by 4 we now know x =2.5.  D is the only possible solution with x=2.5 (5/2) but to solve for y you plug 2.5 in to an equation as x so) x-2y=11

                                                                           2.5-2y=11

                                                                            -2y=8.5                                                                        Answer D (5/2,-17/4)                                      y=-17/4 (4.25)
