Which of the following statements is true?

Question

A.
y + z is an equation and x + y + z is an expression.
B.
5 and x + 3 = 1 both are expressions.
C.
y + z is an expression and x + y + z = 5 is an equation.
D.
5 and x + 3 = 1 both are equations.

Answer 1

The correct statement is:

C. y + z is an expression and x + y + z = 5 is an equation.

Here's the reasoning for each option:

A. y + z is an equation and x + y + z is an expression.
This is false; y + z is an expression, and x + y + z is also an expression.

B. 5 and x + 3 = 1 both are expressions.
This is false; 5 is an expression, but x + 3 = 1 is an equation.

C. y + z is an expression and x + y + z = 5 is an equation.
This is true; y + z is an expression, and x + y + z = 5 is an equation since it equates the expression to the value 5.

D. 5 and x + 3 = 1 both are equations.
This is false; 5 is an expression, not an equation.

So, the true statement is C.
