Roll 1: 1 number out of 6 total numbers = 1/6
Roll 2: 1 number out of 6 total numbers = 1/6
Roll 3: 1 number out of 6 total numbers = 1/6
Roll 4: 1 number out of 6 total numbers = 1/6
Roll 1 AND Roll 2 AND Roll 3 AND Roll 4
1/6 x 1/6 x 1/6 x 1/6 = 1/1296
Answer: Your Answer to the equation is in the picture below.
Step-by-step explanation:
Let's set up a proportion.

Then solve for x:
12 x 800 = 9600
9600/100 = 96
96 is 12% of the 800 students. :)

We want to use substitution to solve
-5x + 4y = 22 (1)
x - 3y = 0 (2)
From (2), obtain
x = 3y (3)
Substitute (3) into (1).
-5(3y) + 4y = 22
-15y + 4y = 22
-11y = 22
y = -2
From (3), obtain
x = 3y = 3*(-2) = -6
Answer: e. (-6, -2)
