Answer:
X=8
Step-by-step explanation:
Cross multiply:
4 * 6 = x * 3
Simplifying
4 * 6 = x * 3
Multiply 4 * 6
24 = x * 3
Reorder the terms for easier multiplication:
24 = 3x
Solving
24 = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
24 + -3x = 3x + -3x
Combine like terms: 3x + -3x = 0
24 + -3x = 0
Add '-24' to each side of the equation.
24 + -24 + -3x = 0 + -24
Combine like terms: 24 + -24 = 0
0 + -3x = 0 + -24
-3x = 0 + -24
Combine like terms: 0 + -24 = -24
-3x = -24
Divide each side by '-3'.
x = 8
Simplifying
x = 8
To answer this question let us first define what a rational and irrational number is. A rational number is basically a number whose decimals are terminating (ie have an end) or repeating (continuously repeats the same pattern.
An example of this from your question would be
5.3 - terminating rational number
5.333333333333..... - repeating rational number
Irrational numbers are basically numbers whose decimals are non terminating and non repeating.
An example would be the square root of 29. When plugged in a calculator this would result in <span>5.3851648071.....
</span>This number goes on and on with no set pattern.
Subtract 100 from both sides
50x = 150 + 30x - 100
Simplify 150 + 30x - 100 to 30x + 50
Subtract 30x from both sides
50x - 30x = 50
Simplify 50x - 30x to 20x
20x = 50
Divide both sides by 20
x = 50/20
Simplify 50/20 to 5/2
<u>x = 5/2</u>
<em>In decimal: 2.5</em>
-21, -46 are the two integers that make a sum of -67
