Naily [24]3 years ago

Answer:

Step-by-step explanation:

Y)  \frac{x+4}{8} = 3

*multiply both sides by 8 - cancels out 8 in denominator*

x + 4 = 24

*subtract 4 from both sides*

x = 20

E) \frac{x-5}{2} = 1

*multiply both sides by 2 - cancels out 2 in denominator*

x - 5 = 2

*add 5 on both sides*

x = 7

N) \frac{x+2}{4} = 2

* multiply both sides by 4 - cancels out 4 in denominator*

x + 2 = 8

*subtract 2 from both sides*

x = 6

Which expression represents a rational number?
Sever21 [200]

Answer:

\frac{2}{7}+\sqrt{121}

Step-by-step explanation:

Given: expressions

To find: expression that denotes a rational number

Solution:

A number of the form \frac{p}{q} where p and q are integers and q\neq 0 is said to be a rational number.

Sum of a rational and irrational number is irrational.

In \frac{5}{9}+\sqrt{18}, \frac{5}{9} is a rational number and \sqrt{18} is an irrational number

So, \frac{5}{9}+\sqrt{18} is not a rational number.

In \pi+\sqrt{16}=\pi+4, \pi is an irrational number and 4 is a rational number

So, \pi+\sqrt{16}  is not a rational number.

In \frac{2}{7}+\sqrt{121}=\frac{2}{7}+11=\frac{2+77}{7}=\frac{79}{7}, \frac{79}{7} is a rational number

So, \frac{2}{7}+\sqrt{121}  is a rational number

In \frac{3}{10}+\sqrt{11}, \frac{3}{10} is a rational number and \sqrt{11} is an irrational number

So, \frac{3}{10}+\sqrt{11} is not a rational number.
