Answer:
-3
Step-by-step explanation:
-4x-16=2x+2
-4x-2x= 16+2
-6x = 18
x = 18/-6 = -3
I hope im right!!
Assuming 0.4 is in fact, 2 divided by 5 (and not an approximation of some number that would require an infinite amount of decimal places to exactly express), then multiplication by 0.4 is the same as multiplying by 2 and dividing by 5.
This means that multiplying any rational number by 2/5 will yield another rational number (as given x/y as an input, where x and y are integers, and multiplying it by 2/5 giving 2x/5y, will mean that 2x and 5y are also integers, and the result is also rational)
If we multiply an irrational number by 2/5, however, the result will be irrational.
So your answer is any number not in the set of rational numbers, multiplied by 0.4, will yield an irrational number.
Answer: 2.5 or 2 1/2.

The answer is b because I took it and got it w
Ok so x+4-1 makes x-1 so i belive the answer could be 1/5
