Mr. Walker asked his students to use the associative property to find an expression that is equivalent to (13 + 15 + 20) + (20 + 47 + 18). The expressions that four students created are shown in the table below. Expressions Generated by Students Student Expression Jeremy (20 + 13 + 15) + (20 + 47 + 18) Layla (20 + 47 + 18) + (13 + 15 + 20) Keith (13 + 20) + (20 + 47 + 18) + 15 Melinda (13 + 15 + 20 + 20) + (47 + 18) How many of the students correctly applied only the associative property to rewrite the expression? one two three four

The correct option is four.

Step-by-step explanation:

The associative property implies that the values are added however we want, i.e. the numbers can be grouped in any way and the answer would still be the same.

The associative property of addition is:

The expression provided is:

(13 + 15 + 20) + (20 + 47 + 18)

The answer provided by four students are:

Jeremy : (20 + 13 + 15) + (20 + 47 + 18)

Layla : (20 + 47 + 18) + (13 + 15 + 20)

Keith : (13 + 20) + (20 + 47 + 18) + 15

Melinda : (13 + 15 + 20 + 20) + (47 + 18)

So, all the four students correctly applied only the associative property to rewrite the expression.

The correct option is four.

the distance between point a and point b is 6 units

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
