81x-29y because you do 65x plus 16x because they both have the variable x at the end. now do 50y plus -21y and since it is a negetive (and it is a negetive it is not just a subtraction sign trust me i have done this many times before and been correct) you get 29 y because they both have the variable y in it. and you can't do anything with a two different variables.

The probability that a blue marble is drawn out of a bag is 3/5. What is the probability that a blue marble is not drawn?
Gemiola [76]
The probability of a blue marble not to be drawn is 2/5

There are 5 marbles in the bag and 3 of them are blue. So to find out the probability of one not being drawn we would take 5/5-3/5 which is equal to 2/5.

Hope this helped! :D

Answer:

-4

Step-by-step explanation:

Slope = y/x

1. y=12 x=-3

  12/-3=-4

2. y=8, x=-2

   8/-2 = -4

3. y=4, x=-1

   4/-1 = -4

4. 0/0 = 0

5. y=-4, x=1

   -4/1 = -4

IgorLugansk [536]

Answer: the percent value-added time for this ride is 16.67%

Step-by-step explanation:

 Given that;

Waiting time for Vera = 35 minutes

Length of Vera's ride = 7 minutes

total processed time will; ( 35 + 7 ) = 42 minutes

the percent value-added time for this ride = ?

so

Percentage value-added time of Vera will be

= (length of the ride / total process time) × 100

we substitute

⇒ (7 / 42) × 100

⇒ 0.16666 × 100

⇒ 16.67%

Therefore the percent value-added time for this ride is 16.67%
