Answer: n = 4
Step-by-step explanation:
The given expression is
2n+4=12
We want to solve for n. The first step is to make 2n stand alone on the left hand side of the equation. This is achieved by subtracting 4 from the left hand side and the right hand side of the equation. It becomes
2n + 4 - 4=12 - 4
2n = 8
The next step is to divide the left hand side and the right hand side of the equation by 2. It becomes
2n/2 = 8/2
n = 4
Answer:
33%
Step-by-step explanation:
Prob(heads) = 1/2
Prob(either red or blue) = 2/3
So Prob( heads and red/blue) = 1/2 * 2/3
= 2/6
= 1/3 which is 33%.
Answer:
It's y = 3
Step-by-step explanation:
Reason why it's not x = 3 is because x is on the left to right or horizontal plane, therefore it would be y because y is on the vertical axis. If using x, it would be a vertical line on x while using y would create a horizontal line.
