What is the sum of rational expressions

Mathematics
1 answer:
rjkz [21]3 years ago
6 0

Since you have a common denominator, just add the numerators and set the sum over the common denominator.

\dfrac{15}{7x} + \dfrac{12}{7x} = \dfrac{15 + 12}{7x} = \dfrac{27}{7x}

There is no common factor of 27 and 7x, so the fraction cannot be reduced.

Answer: C. \dfrac{27}{7x}

Probability of rolling factors of 20
Marizza181 [45]
If you are rolling a single six sided die numbered 1-6, you find that only 1,2,4, and 5 are factors of 20. Now the theoretical probability of an event is the ratio comparing the number of desired outcomes to the total outcomes possible.

In this case: we have 4 desired outcomes out of a total 6 outcomes possible with a single roll the die.. therefore, the probability you seek is \frac{4}{6} = \frac{2}{3} or approximately 67%.

What is Add and Simply 7/4 + 5/6 =
Pani-rosa [81]
Simple, first find a common denominator, 24.

So,

7/4*6= 42/24
and
5/6*6=30/24

Then just add, 

42/24
+
30/24

Making it 72/24.

72/24=3

Thus, your answer is, 3.
