5 is the probability because there are 5 coins in total unless it’s 5 times 5 then 25 I think
Answer: its a
Step-by-step explanation: the only one that makes sense
Simplifying
12x + -8x = 12
Combine like terms: 12x + -8x = 4x
4x = 12
Solving
4x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x = 3
Simplifying
x = 3
You can divide everything by “4” which would end up with the answer being
5-2x over 1 which would be just 5-2x
X = 8
We’ll combine like terms by getting all the x terms on the right, all the digits on the left.
16 = 2x
Divide both sides by 2
x = 8
