Answer:

(3,2)

Step-by-step explanation:

2x+5y=16

3x-5y=-1

Subtract 2x from the first equation

5y=16-2x

Substitute the given value of 5y into the equation

3x-(5y)=16

3x-(16-2x)=-1

Solve for x

3x-(16-2x)=-1

3x-16+2x=-1

5x-16=-1

5x=15

x=3

Substitute the given value of x into the equation

3x-5y=-1

3*3-5y=-1

Solve

3*3-5y=-1

9-5y=-1

-5y=-10

y=2

What is the probability that when you roll the number cube (6 sides) twice, you will get 1 on both rolls?
Romashka-Z-Leto [24]

Answer:

1/36

Step-by-step explanation:

When you roll it the first time, the chances to get a 1 is 1/6.

when you roll it the second time, the chance is still 1/6, but the chance of rolling one twice in a row, is the product of the probabilities:

1/6 * 1/6 = 1/36
