-20+20w=73
You need to get your variable by itself. Try to section your problem off if you need to. I always like to do my order of operations backwards. The inverse operation of -20 is adding 20 so to cancel that out you need to add 20 to each side. Now you are left with 20w=93.Now you need to get rid of the 20. The inverse of multiplying is dividing. So divide both sides by 20. You are left with 1w=4.65. Which is the same w=4.65 or you could say w=4 13/20. Hope this helps.

Then subtract $13 $250 - $13 = $237
Then add $26! $237 + $26 = $263!
b. Use a calculator to change the answer to decimal form. Round the answer to the nearest tenth. Using this decimal number, write a sentence to explain the meaning of the answer in this situation.
Answers
Let: a = 12; b = 8
Substituting the values:
c = √(12² + 8²)
c = √(144 + 64)
c = √(208)
c = √(16)(13)
c = +-4√13
The positive root indicates the answer. The car is 4√13 miles from the starting point.
b. Using a calculator to simplify c = +-4√13 in decimal form would yield:
c = 14.42 miles.
The car is now 14.42 miles away from the starting point.

Robert paints 1/6 of a room in an hour.
Julio paints 1/8 of a room in an hour.
Working together, they can paint (1/6 + 1/8) room/hour =
(4/24 + 3/24) room/hour =
7/24 of a room per hour.
7/24 of a room per hour means
24 hours / 7 rooms =
(24 / 7) (hour/room) = (3 and 3/7) hour per room.
1/6*(6*8*x)+1/8(6*8*x)=1/x(6*8*x)
8x+6x=48

divide each by 14
x=48/14
