Answer:
33/22=3/2
Step-by-step explanation:
11/2×3/11we change the denominator to nominator and we change the sign to multiplication
33/22when we simply it 3/2
Answer: Choice D. 
========================================================
Work Shown:
We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents
This is what the steps could look like

The final result is in scientific notation as the coefficient c is restricted such that 
Answer:
x=5
Step-by-step explanation:
To find x, you need to divide 7 by the coefficient which is 1.4. 7/1.4=5
The answer is c I know cause i done it
You have to add the numbers that have like terms together. For example you would add the 14 y and the -134y and get -120y and then you would add the 112, 2, and the -12 and get a 102
So your answer would be -120y+102
