if 2/3=x/12, what is the value of x?​

Answer:

Step-by-step explanation:

(245 - 4) - 3 x (2 + 1)

   241 - 3 x 3

      241 - 9

         232

or if u wrote the problem wrong

(45 - 4) - 3 x (2 + 1)

   41 - 3 x 3

      41 - 9

        32

actually comment what the actual equation is and I'll solve that, bc I don't think you typed it right

Answer:

Rational numbers are the numbers which are integers and fractions

Irrational numbers are the numbers whose expression as a fraction is not possible

Examples of Rational Number

1/9 – Both numerator and denominator are integers.

7 – Can be expressed as 7/1, wherein 7 is the quotient of integers 7 and 1.

√16 – As the square root can be simplified to 4, which is the quotient of fraction 4/1

0.5 – Can be written as 5/10 or 1/2 and all terminating decimals are rational.

0.3333333333 – All recurring decimals are rational.

Examples of Irrational Number

√2 – √2 cannot be simplified and so, it is irrational.

√7/5 – The given number is a fraction, but it is not the only criteria to be called as the rational number. Both numerator and denominator need to integers and √7 is not an integer. Hence, the given number is irrational.

3/0 – Fraction with denominator zero, is irrational.

π – As the decimal value of π is never-ending, never-repeating and never shows any pattern. Therefore, the value of pi is not exactly equal to any fraction. The number 22/7 is just and approximation.

0.3131131113 – The decimals are neither terminating nor recurring. So it cannot be expressed as a quotient of a fraction.

Answer:

It's D

Step-by-step explanation:

2t - 30([tex]\frac{1}{5}[/tex]) = 20

2t - [tex]\frac{30}{1}[/tex] ([tex]\frac{1}{5}[/tex]) = 20

2t - [tex]\frac{30}{5}[/tex] = 20

2t - 6 = 20

2t - 6 + 6 = 20 +6

2t = 26

[tex]\frac{2t}{2}[/tex] = [tex]\frac{26}{2}[/tex]

t = 13

Answer:

s=  -5

Step-by-step explanation:

have a good day

Answer:

Step-by-step explanation:

subtract 28 on both sides that will cancel the 28

-35 = 7s, divide both sides by 7, this cancels the 7

- 5 = s

s=-5

Answer:

The star equals 96

Step-by-step explanation:

The star will be equal to 5x-14 because they are vertically opposite.

The two exterior angles are supplementary.  Set up the equation

5x - 14 + 3x + 18 = 180        Combine the terms on the left.

8x + 4 = 180                        Subtract 4 from both sides

8x = 180 - 4                         Combine

8x = 176                               Divide by 8

x = 176 / 8

x = 22

===================

5x - 14

5*22 - 14

Answer:

finite is numbers that stop at some point, like randomly... 23. infinite is numbers that go on forever like infinity.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The question is asking for the absolute value of -1. The absolute value is the distance of a number from 0. Think of a number line. -1 is one place away from 0, so the absolute value of -1 is 1. Therefore, the statement is not true.
