Question

which of these can be written as an equation 1:three is less than twice a2:two times 0.75 plus m3:half the product of five and j4:four times n is 24

Answer 1

Option 4 is the right answer

Step-by-step explanation

To answer the question, we have to translate each of the sentences into mathematical statements.

A mathematical equation must contain an equal to sign.

1. Three is less than twice a

This can be written as:

3 < 2 * a

=> 3 < 2a

This is not an equation, it is an inequalaity.

2. Two times 0.75 plus m

This can be written as:

2 * 0.75 + m

=> 1.5 + m

This is not an equation, it is an expression.

3. Half the product of five and j

This can be written as:

1/2(5 * j)

=> 5j/2

This is not an equation, it is a term.

4. Four times n is 24​

This can be written as:

4 * n = 24

=> 4n = 24

This is an equation.

Option 4 is the right answer.
