Answer: 35,40,45,50,55
That is the answer to the 1st part.
Step-by-step explanation:
If x-10=15 and x=25
then the Hypothesis would be true.
25-10=15
the answer if those two are the answers it'd be A.
Answer: D
Step-by-step explanation:
To find the difference, we want to make sure both denominators are equal.
Now that the denominators are equal, we can distribute and multiply out.
With the fractions multiplied out, we can actually put it into one large fraction.
Let's subtract the top expression.
This may seem like our final answer, but we can actually factor out an 3x in the numerator and denominator.
With the 3x factored out, they cancel out because 3x/3x=1.
Our final answer is:
Answer:
Rational
Step-by-step explanation: it equals 40, and 40 is rational
