DochEvi [55]

Answer:

$3\frac{1}{2}-rational$

$\pi -irrational$

$-\frac{2}{3}-rational$

$\sqrt{16} -rational$

$\sqrt{3} -irrational$

$18-rational$

$0.625-rational$

$0.987987987...-rational$

Step-by-step explanation:

Rational numbers:

-are all numbers you can write as a quotient of integers $\frac{a}{b}$ , $b\neq 0$

-include terminating decimals. For example, $\frac{1}{8}=0.125$

-include repeating decimals. For example, $\frac{1}{3} =0.33333....$

Irrational numbers:

-have decimal representations that neither terminate nor repeat. For example, $\sqrt{2}=1.414213....$

-cannot be written as quotients of integers

2x-14y= -16 solve for x ..

Kruka [31]

2x - 14y = -16

Move all the terms without the variable on the other side of the equation. Add 14y to both sides of the equation.

2x = -16 + 14y

Divide both sides by 2.

x = -8 + 7y is your answer.
