Amount of decreased water = 3/10
Then, it would be 3/10 * 100 = 30%
So, your answer is 30%
Move all terms to the left side then set equal to 0. then set each factor equal to 0. k=-1, -5
Pretty good, How about you
3x/(x+1) + (x+1)/(2x) + (5/x)
To find the least common denominator, we multiply the denominators that cannot factor into eachother. x, the denominator in 5/x, fits into 2x, so we do not need to multiply this number.
Therefore, the least common denominator is:
2x(x+1)
The first term will be multiplied by 2x/2x
The second term will be multiplied by (x+1)/(x+1)
The third term will be multiplied by 2(x+1)
You would first look at the tens place numbers; 10 and 30. and add them together making 40. after that you'd take the ones places and add them together; 7 and 8. add those together and you'd get 15. to finish you just need to add the two numbers together 40 and 15.
