19 4/12 + 17 2/11 - 16 6/9 = The answer was actually given to me through a download worksheet but I can't come up with it so I need it totally worked out. My answer comes to 20 -5/33 but the answer should not have a negative numerator in it and the answer given was 19 28/33

19 28/33

Step-by-step explanation:

lets work out the whole number parts first:

= 19 + 17 - 16 = 20.

4/12 + 2/11 - 6/9

= 1/3 + 2/11 - 6/9

Find the LCM of the denominators:

3 = 3

11 = 11

9 = 3*3

- so the LCM is 3*3*11 = 99.

So we have:

33/99 + 18/99 - 66/99

= 51/99 - 66/99

= -15/99

= -5/33

So the answer is  20 - 5/33

= 19 28/33

You just had to subtract 5/33 from 20.

answer: i guess 105 degrees?

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
