Which expression represents a rational number? StartFraction 5 Over 9 EndFraction + StartRoot 18 EndRoot
Pi + StartRoot 16 EndRoot
StartFraction 2 Over 7 EndFraction + StartRoot 121 EndRoot
StartFraction 3 Over 10 EndFraction + StartRoot 11 EndRoot

Step-by-step explanation:

Given: expressions

To find: expression that denotes a rational number

Solution:

A number of the form where p and q are integers and is said to be a rational number.

Sum of a rational and irrational number is irrational.

In , is a rational number and is an irrational number

So, is not a rational number.

In , is an irrational number and 4 is a rational number

So,  is not a rational number.

In , is a rational number

So,  is a rational number

In , is a rational number and is an irrational number

So, is not a rational number.

the answer is x equals 50, this is because the two angles are the same measurements because they are vertical angles. in corresponding angles, vertical angles are two angles with one diagonally above another. those two angles will be the same measurements.

110 - 10 = 100

100 / 2 = 50

x   = 50

110 = 2(50) + 10 = 110

110 = 110

can u give brainliest if i'm correct?
