Step-by-step explanation:
2x + y = 2 <em>subtract 2x from both sides</em>
2x - 2x + y = 2 - 2x
y = -2x + 2
(m = -2, b = 2)
-3x + y = 4 <em>add 3x to both sides</em>
-3x + 3x + y = 4 + 3x
y = 3x + 4
(m = 3, b = 4)
.........................................
Total squares= 12
1x + 2x = 12
3x = 12
3x/3 = 12/3
x = 4
1x4 = 4
2x4 = 8
So. C is the answer
The answer is B I hope this helps and you have a great day! :D
Answer:
Third choice, 3/4
Step-by-step explanation:
Add all the cubes together, 12 + 5 + 3 = 20
There's a 12/20, which is 3/5, chance you'll get a green cube
5/20, which is 1/4, chance you'll get a blue cube
And there's a 3/20 chance you'll get a yellow cube
The probability of not getting a blue cube is 12/20 + 3/20 = 15/20 = 3/4
