Answer:
40°F
Step-by-step explanation:
When Tyrese fell asleep one night, the temperature was 24°F.
When Tyrese awoke the next morning, the
temperature was -16°F.
Letting + denote a rise in
temperature and - denote a drop in temperature, what was the change in temperature from the time Tyrese fell asleep until the time he awoke?
The temperature dropped from a high temperature to a low one : from 24° to -16°
This can be expressed mathematically as 24 - (-16), with - denoting a drop in the temperature
=24-(-16)
=24+16
=40°F

Your expression is ambiguous.
Do you mean a + (2/5)a^2 + 3?
or perhaps a + 2 / (5a^2) + 3? Use parentheses for added clarity.
If you meant a + (2/5)a^2 + 3, then
(2/5)a^2 + 1a + 3 (this can't be simplified further)
+ 1 = 3
First, multiply both sides by 3. / Your problem should look like: x + 3 = 9.
Second, subtract 3 from both sides. / Your problem should look like: x = 9 - 3.
Third, simplify 9 - 3 to 6. / Your problem should look like:
x = 6, which is your answer.
