Question

.) Arjen lives in Wisconsin. He said it was -10 degrees in the morning and it dropped 15degrees by midnight. What was the temperature at midnight?a. Show a mathematical statement to represent this situation and evaluate it.b. Write an inequality statement for -10 and 15 that uses the >< symbol.c. What is the absolute value of the morning temperature? Show a mathematicalstatement and evaluate it.

Answer 1

So,

The temperature was -10 degrees in the morning. Given that it dropped 15 degrees by midnight, we could substract 15 to -10 to find the temperature at midnight:

`-10-15=-25`

The temperature at midnight was -25 degrees.

b. Clearly,

`-10<15`

c. The absolute value of the morning temperature is:

`|-10|=-(-10)=10`

That's because:
