Answer:

Question 1: x = -75/38

Question 2: -5/6 X (-5/8) X 6/5 = 5/8

Step-by-step explanation:

Question 1:  3 4/5x - 2 1/2 for x = -10

Given equation is in whole number form so by simplifying we get:

19/5x - 5/2 = -10            (As 5*3 + 4 = 19  and 2*2+1 = 5)

Now Add 5/2 on both sides we get:

19/5x - 5/2 +5/2 = -10 + 5/2

19/5x  = -10 + 5/2

Taking LCM we get:

19/5x = (-20+5)/2

19/5x = -15/2

Multiply both sides by 5/19

x = -15/2 * 5/19

x = -75/38

Question 2:

= -5/6 X (-5/8) X 6/5

Multiplying first 2 fractions we get:

= 25/48 X 6/5   ("-" multiplied by "-" gives "+")

  • 25 in numerator will be cancelled from 5 in denominator giving 5
  • 6 in numerator will be cancelled by 48 in denominator giving 8

= 5/8 X 1/1

Multiplicative identity

= 5/8

I hope it will help you!

Rational numbers with distribute property
Svetradugi [14.3K]

I'm not sure what this means. If you have choices you should list them.

(1/2)*(1/4 + 1/6) is an example of what should be given. There are two ways to solve this.

1. Use the distributive property.

1/2*1/4 + 1/2* 1/6

1/8 + 1/12 Which can be added using the LCD of 24

3/24 + 2/24 = 5/24

Method 2

Add what is inside the brackets first.

1/2 ( 1/4 + 1/6)

1/2(3/12 + 2/12 = 5/12

Now multiply by 1/2

1/2(5/12) = 5*1/(12 * 2) = 5 / 24 Same answer.

(X+5)+(x-5)=56 what does x=?
kirill115 [55]

Answer:

x=28

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+5+x−5=56

x+5+x+−5=56

(x+x)+(5+−5)=56(Combine Like Terms)

2x=56

2x=56

Step 2: Divide both sides by 2.

2x/2=56/2

x=28

A set X consists of all real numbers greater than or equal to 1. Use set-builder notation to define X.
vitfil [10]

Theory:

The standard form of set-builder notation is <span>
 
{ x | “x satisfies a condition” } </span>

This set-builder notation can be read as “the set of all x such that x (satisfies the condition)”.

For example, { x | x > 0 }  is equivalent to “the set of all x such that x is greater than 0”.

 

Solution:

In the problem, there are 2 conditions that must be satisfied:

<span>1st: x must be a real number</span>

In the notation, this is written as “x ε R”. Where ε means that x is “a member of” and R means “Real number”

 

<span>2nd: x is greater than or equal to 1</span>

This is written as “x ≥ 1”

 

Answer:

Combining the 2 conditions into the set-builder notation:

<span>X = { x | x ε R and x ≥ 1 } </span>
