Question

Marta said 50 + one-half m = 120 is an equation, while Maribel argued that it is an expression. Determine who is correct and explain why.

Answer 1

Answer:

Marta is correct. This is an equation. The statement includes an equal sign. Equations include an equal sign, expressions do not include an equal sign.

Step-by-step explanation:

Answer 2

Marta is correct because of the following reasons-

• As per Marta, 50+m/2=120 is an equation that is true because it contains the sign of equality.
• An equation involves quantities that are connected by that equal sign.
• However, in an expression, only the numbers, variables, or terms are related randomly.
• From the given information, 50+m/2 is an expression and is a part of the equation.
• So, an equation is a combination of one or many expressions.
