Step-by-step explanation:
start with factoring.
5x+15-9x+4
then solve
-4x+19
Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.
For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.
You would need to come in 583.6 or 584 times
there are 360 degrees in a complete circle
360/18 = 20
so the answer is C
