To solve the problem we will first make an expression, and then compare the other statements' expressions with this.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The correct option is D.
Statement - The algebraic expression x minus 21. 5
The given statement can be written as,
x - 21.5
A.) 21. 5 decreased by x
This can be written as 21.5-x, which is not the desired algebraic expression.
B.) x more than 21. 5
This can be written as 21.5+x, which is not the desired algebraic expression.
C.) 21. 5 minus x
This can be written as 21.5-x, which is not the desired algebraic expression.
D.) x less 21. 5
This can be written as x-21.5, therefore, this is the desired expression.
Hence, the correct option is D.
