Answer:

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

Step-by-step explanation:

Since, a real number is called rational number if it can be expressed in the form of \frac{p}{q},

Where, p and q are integers,

S.t. q ≠ 0,

If the number is not a rational number then it is irrational,

Now, the sum or difference of two rational numbers is a rational number,

While, the sum or difference of a rational number and an irrational number is an irrational number.

∵ √18, √11 and \pi are irrational numbers,

Also, \frac{5}{9}, \sqrt{16} and \frac{3}{10} are rational number,

\implies \frac{5}{9}+\sqrt{18},\pi+\sqrt{16}, \frac{3}{10}+\sqrt{11}\text{ are irrational numbers}

Now,

\frac{2}{7}\text{ and }\sqrt{121}\text{ are rational numbers}

Hence,

\frac{2}{7}+\sqrt{121}\text{ is rational number}

White raven [17]
If the original price was 'p', the new price would be 'p - 10%p' or 'p - 0.1p'. We know this is equal to 305, so 'p - 0.1 p = 305' would be the equation.

The sum of 3 consecutive even integers is 576. Find the integers
alisha [4.7K]
You can write the equation
x+1+x+3+x+5=576
Combine like terms
3x+9=576
Subtract 9 from both sides
3x+9-9=576-9
3x=567
Divide both sides by 3
3x/3=567/3
x=189
 The first integer is 190, the second is 192 and the third is 194 (enter it into the original equation to get those answers)
