Answer:
Out of the 3 that were listed, the "conversion" that is invalid is 1 meter = 10 millimeters.
Step-by-step explanation:
First: Well, for something like this, you don't really need steps, you just need to know how to do process of elimination and also your conversions:
We know that 1 meter is 100 centimeters
We know 1 kilometer is 1000 meters
We know that 1 meter is 10 millim....... Wait. Do we know that?
No! 1 meter is not 10 millimeters, it's 1000 millimeters. So 1 meter = 10 millimeters is invalid.
If you ever need a converter, use this link: https://www.google.com/search?q=centimeters+to+inches&rlz=1CAFQZI_enCA835&oq=centim&aqs=chrome.2.69i57j0l5.9328j0j7&sourceid=chrome&ie=UTF-8

Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,

Answer:
20/27
Step-by-step explanation:
2/3 is the dividend,
9/10 is the divisor,
20/27 is the quotient.
Remember: 2/3 divided by 9/10
2/3 ÷ 9/10 = 2/3 x 10/9. Hence, instead of performing the division, multiplying 2/3 with the reciprocal of 9/10 is the easiest method to find what is 2/3 divided by 9/10 in fraction form.
