25. Because (30/50)/(2)= 15/25
15= cars washed
25 = lawns mowed
PEMDAS
since we don't have exponentes or paretnahsees we do
muliplictaion or division whichever comes first (since division is just multiplication of a fraction)
addition or subtraction whichever comes first (since subtraction is adding a negative)
so
multiply/divide
0 times 3=0
9/3=3
now we have
5-0+3
add/subtract
5-0=5
5+3=8
answer is 8
This depends on the question itself. But I will assume and provide an answer.
If arc CD is made from the central angle intercepting the perimeter of the circle( so if the central angle is CBD, then the arc is from the two endpoints of the angle) that would mean that the arc is 35 degrees. If the two endpoints of the arc are NOT the two points from the angle that lie on the circle, then I cannot provide an answer without a picture.
To sum it up, if the arc begins and ends on the two endpoints of the angle, then it is 35 degrees. Unless it goes the long way around, then it would be 325, but that's unlikely to be the case.
Answer:
x=14/3
Step-by-step explanation:
5x-y=6
+ -2x+y=8
----------------
5x+(-2x)-y+y=6+8
5x-2x-y+y=6+8
3x=14
x=14/3
I apologize if something is incorrect, please me know how to fix it. Thank you!
