70%
Step-by-step explanation:
14 out of 20 is 14/20=7/10
7/10 is 70%
whatever% of anything is just (whatever/100) * anything.
800+1250+120+625+65 gives us 2860.

Answer:
22,500 =2p
Step-by-step explanation:
Because the price of the new car is the price of the old car times 2.
22,500 =2p
First you get P alone. P is being multiplied by 2 so you divide it by 2 so it cancels out.
11250 = p
When you do something to one side of the equation you do the same to the other side so they are still equal to each other.
Answer:
angle AOD + 170=180 (sum of angles on a straight line)
angle AOD=180-170
angle AOD=10
Angle BOC(4x)+ 170= 180 (sum of angles on a straight line )
angle BOC(4x) =180-170
4x=10
4x/4=10/4
x=2.5
