Short Answer

Expert verified

The value of the expression is: $2 .75 + 3 .5 + 4 .25 + 1 .5 = 12$ .

Step by step solution

– Given information.

Given expression is:

$2.75 + 3.5 + 4.25 + 1.5$

– Write the concept.

The substitution property for multiplication, addition and subtraction is:

$\begin{matrix} a \cdot b = c \\ a \pm b = c \end{matrix}$

The commutative property of addition is:

$a + b = b + a$

– Evaluate the expression.

The expression $2.75 + 3.5 + 4.25 + 1.5$ can be solved in below:

$\begin{matrix} 2.75 + 3.5 + 4.25 + 1.5 = (2.75 + 4.25) + (3.5 + 1.5) [Commutative Property] \\ = (7) + (5) [Substitution Property] \\ = 12 [Substitution Property] \end{matrix}$
