Parenthesis first so, 64/8(10)+5, next 64/8 because it's division and it's first, 8(10)+5, next is 8(10) so 80+5, lastly 80+5 is 85.
If a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.
Given that a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5.
We are required to find the probability of getting red balls.
Probability=Number of items/Total items
Probability of getting red balls=1-(Probability of getting white balls +Probability of getting black balls)
=1-(3/10+2/5)
=1-7/10
=3/10
Hence if a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.

X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5
X = 2.8
Answer:
12 inches squared
Step-by-step explanation:
If it is 6 inches by 2 inches, then you multiply 6 by 2 to get 12 inches squared.
50% because there are 4 routes and 2 take 30 minutes, 2/4 = 50/100 = 50%
