Question

solution set of 5x-9<15 where x€whole number​

Answer 1

Answer:

x< 6/5 or 1 whole 1/5

Step-by-step explanation:

5x-9<15

5x<15+9

5x<6

x<6/5

Answer 2

Solution set of  5x-9<15  is  x = { 0 , 1 , 2 , 3 , 4} where x ∈ Whole numbers

Given:

• 5x-9<15
• x ∈ Whole numbers

To Find:

• Solution set

Solution:

• Whole numbers are non negative integers
• Whole numbers are natural numbers including 0

5x-9<15

Step 1:

Add 9 both sides

5x-9 + 9 < 15 + 9

=> 5x < 24

Step 2:

Divide both sides by 5

5x/5  < 24/5

=> x < 24/5

=> x < 4.8

Step 3:

List all the whole numbers less than 4.8

x = 0 , 1 , 2 , 3 , 4

Hence x = { 0 , 1 , 2 , 3 , 4}

Solution set of  5x-9<15  is  x = { 0 , 1 , 2 , 3 , 4}  where x ∈ Whole numbers
