Question

Rachel boils water to make tea. After the tea is finished steeping, she puts the container of hot tea in the refrigerator. The hot tea raises the normal temperature of the refrigerator, 34 degrees, by more than 3 degrees. If r represents the raised temperature, which statements about the scenario are true? Check all that apply.

The inequality r + 3 > 34

Answer 1

its the 2 and 3

Explanation:

Answer 2

The inequality r – 34 > 3 can be used to represent the situation.

The raised temperature could be 40 degrees.

Explanation:

The choices are

• the inequality r + 3 > 34 can be used to represent the situation.
• the inequality r – 34 > 3 can be used to represent the situation.
• the raised temperature could be 40 degrees.
• the raised temperature could be 37 degrees.
• the graph of the solution set would be shaded to the left.

Notice that the inequality which represents this situation is

`r>34+3`

Because the temperature increases more than 3 degrees.

So, the second choice is correct, because it's the expression that represents the problem.

Now, the initial temperature of the refrigerator was 34°, if it increases more then 3 degrees, it means the temperature can be greater than 37°, therefore, the third choice is correct, because 40° is greater than 37°.

At last, the graph of the inequality is shaded to the right, because the inequility symbol is "greater than".
