Answer: x=36

Simplifying

6x + 27 = 7x + -9

Reorder the terms:

27 + 6x = 7x + -9

Reorder the terms:

27 + 6x = -9 + 7x

Solving

27 + 6x = -9 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

27 + 6x + -7x = -9 + 7x + -7x

Combine like terms: 6x + -7x = -1x

27 + -1x = -9 + 7x + -7x

Combine like terms: 7x + -7x = 0

27 + -1x = -9 + 0

27 + -1x = -9

Add '-27' to each side of the equation.

27 + -27 + -1x = -9 + -27

Combine like terms: 27 + -27 = 0

0 + -1x = -9 + -27

-1x = -9 + -27

Combine like terms: -9 + -27 = -36

-1x = -36

Divide each side by '-1'.

x = 36

Simplifying

x = 36

Explain why percents are rational numbers.
levacccp [35]
<span>Yes since percents can be decimals and these decimals can be illustrated as fractions hence, vice-versa.

80%= 0.8 = 4/5

A rational number is any number or numerical value which can be possibly stated in a fraction form of numbers, it basically has a numerator and denominator. Furthermore, the values of the numerator and denominator is integers and doesn’t equal to 0. In this given case of 8 over 5 or 8/5 this fractional number can still be expressed in a standard numerical form with a decimal as 1.6 without repeating decimal values. Unlike irrational numbers which is not possible, take for instance 3.1416… and so on which cannot be “fractionized”.<span>

Formula for the circumference: 
C = π d
Use the estimate of 3.14 for π: 9.42 = 3.14 d 
Divide both sides by 3.14: d = 9.42 / 3.14 They have very conveniently given you a round number: d = 3  so your answer is A
