83 tens x 2 tens = 166 would it be 166 hundreds, tens, ones, hundredths, thousands, thousandths, or tenths?

Okay. 83 tens is equivalent to 830 and 2 tens is 20. Mind you that 10 tens equal 100. 830 * 20 is 16,600, which is equivalent to 166 hundreds. Tens, ones, thousandths, and tenths make zero sense, because those values are too small and 166 thousands equals 166,000. The answer is hundreds.

This equation can be simplified to: x=2 y

y=1/2x

Yes, this is linear
