Question

Ellen drew a graph showing the solution to an inequality. A number line going from negative 1.25 to positive 0.75. An open circle is at negative 0.75. Everything to the left of the circle is shaded. Then she wrote four possible inequalities. 3.25 less-than 2.5 + r 3.25 greater-than 2.5 + r Negative 3.25 less-than negative 2.5 + r Negative 3.25 greater-than negative 2.5 + r Which inequality does Ellen’s graph show the solution to? 3.25 less-than 2.5 + r 3.25 greater-than 2.5 + r Negative 3.25 less-than negative 2.5 + r Negative 3.25 greater-than negative 2.5 + r

Answer 1

Answer:

  Negative 3.25 greater-than negative 2.5 + r

Step-by-step explanation:

The solution Ellen drew is ...

  r < -0.75

This is the solution to ...

  -3.25 > -2.5 +r

  -0.75 > r . . . . . . . add 2.5 to both sides

Comment on the problem text

Math expressions are much easier to read if you use math symbols to write them.

Answer 2

Answer:

3.25 greater-than 2.5 + r

Step-by-step explanation:

It should be: r < 0.75

3.25 > 2.5 + r

r < 0.75
