Answer:
(4.2x100).(5.7x100) = 239.400
Step-by-step explanation:
We need to determine the product of (4.2x100).(5.7x100).
We know that when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For that reason, we can multiply all together, and the result will be the same regardless of the order of the multiplicands:
Then:
(4.2x100).(5.7x100) = 4.2x100x5.7x100 = 420x570= 239.400
I believe it is B I think.
Its B.6 because when you plug in 1 for y the equation is 3x-1=17 and you have to cancel out y to get 3x=18 by itself because you have to add 1 to the 17 since you canceled it out of the equation then you are left with 3x=18 and you divide both sides by 3 and then 18 divided by 3 is 6 so x=6
