The temperature drops 28°. After the drop, the thermometer reads 48°. Which integer represents the number of degrees the temperature drops?

A)

-28°

B)

-20°

C)

28°

D)

48°

-28° represents the number of degrees the temperature drops. Correct option A) - 28°.

Step-by-step explanation:

Here we have, The temperature drops 28°. After the drop, the thermometer reads 48°. Let us suppose that initially the temperature was x, and after drop it's 48 i. e.

x - (28) = 48

We are supposed to tell that how from how many temperatures drop is there, which is - 28° where 28 tells us about the value or number that temperature is dropped & - (minus) sign indicates that there is fall or drop in temperature. So, drop in temperature is given by - 28°.

Hence, - 28° represents the number of degrees the temperature drops. Correct option A) - 28°.
