2. On Saturday morning the temperature outside was 4 degrees Fahrenheit. By noon, the temperature had risen 12 degrees, and then at 9 P. M., it dropped 17 degrees. Write an expression that this situation describes. What was the temperature at 9 P. M.? Explain how you could use the vertical number line as a tool to solve the problem.

it is 16 degrees outside then take away the 17 from the 16 and the answer is 1 degree

step-by-step explanation: examine the two-step equation.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
