Step-by-step explanation:

The number which is "three fewer than four times a number is five more than twice the number" is 4.

Linear Equation

The equation having the highest power of its variables as 1 is known as a linear equation.

How do we find the number?

Let the required number be x.

The given condition is - "Three fewer than four times a number is five more than twice the number."

Based on the given condition we will form an equation and solve it for x to find the required number.

The resulting linear equation is,

4x-3 = 2x+5

4x-2x = 5+3

2x = 8

x = 4

Hence, the required number is 4.

Answer:

k > 24

Step-by-step explanation:

To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.

Answer:

k = 24

Step-by-step explanation:

k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.
