There are 8 letters total and 1 is J
so 7/8 probability of not picking the J
Fraction: 7/8
decimal: 0.875
percentage: 87.5%
The speed of the plane is 200 mph.
We start out with the formula d=rt, where d is distance, r is rate (speed) and t is time. We know the time is the same for both vehicles, so we will solve this formula for t:
d=rt
Divide both sides by r:
d/r = t
Since the time is the same, we will have a proportion in the form
d/r = d/r
The speed of the car is x, and it travels 150 miles. The speed of the plane is 150 faster than x, or x+150, and it travels 600 miles:
150/x = 600/(x+150)
Cross multiplying we have:
150(x+150) = 600*x
150x + 22500 = 600x
Subtract 150x from both sides:
150x + 22500 - 150x = 600x - 150x
22500 = 450x
Divide both sides by 450:
22500/450 = 450x/450
50 = x
The speed of the car is 50, and the speed of the plane is 50+150 = 200
Answer:

Answer:
one solution
Step-by-step explanation:
3 -2x=5-x+3+4x
Combine like terms
3-2x = 8+3x
Add 2x to each side
3-2x+2x = 8+3x+2x
3 = 8+5x
Subtract 8 from each side
3-8 =8+5x-8
-5 =5x
Divide by 5
-5/5 = 5x/5
-1 =x

Answer:
The ratio is 5:8.
Step-by-step explanation:
Since we are looking for books and tennis balls, we have to look at how many there are. There are 5 books and 8 tennis balls. We're looking for the ratio of books to tennis balls, so it has to be in that order. 5:8
I hope this helped! :-)
