X=40 because you set all the degrees equal to 360 degrees because its a circle :)
I know that you should use PEMDAS, what grade are you in this sems advances for you
Remove parentheses.
-3/8 -1/6
Find the Least Common Denominator (LCD) of 3/8, 1/6. In other words, find the Least Common Multiple (LCM) of 8,6.
LCD=24
Make the denominators the same as the LCD.
- 3x3/8x3 - 1x4/6x4
Simplify. Denominators are now the same
-9/24 - 4/24
Join the denominators
-9-4/24
Simplify
-13/24
Answer:
for every 1000 people, the maximum noise level goes up by 1.5
