Answer:
(x + 12) / 4
Explanation:
This was the way I was taught, hopefully it helps you.
y = 4x - 12
x = 4y - 12
x + 12 = 4y
(x + 12) / 4 = y
Answer:
Step-by-step explanation:
P(AUB)=P(A)+P(B)+P(A∧B),P(A∧B)=0 as both the events are independent.
P(AUB)=1/2+1/3=(3+2)/6=5/6
Answer:
x = 10
Step-by-step explanation:
1) Subtract x from both sides.
4x − x = 30
2) Simplify 4−x to 3x
3x = 30
3) Divide both sides by 3
x = 
4) Simplify
to 10
x = 10
