500-400=100
Cool! So a coin has 2 sides, so therefore there is only a 50/50 chance. So 1/2 probability for getting heads on one coin toss. I do not know how to insert a probability tree but they are helpful! So 3 tosses, and if there’s only 2 possible outcomes for 1 toss, 2*3 which equals 6! 2 possible outcomes * 3 tries will give you the total possible outcomes. So you only need to land 1 head, so 3(possible heads)/6(total possible outcomes). Your answer is 3/6, or 1/2 simplified.
First, create an equation with the criteria given.
If we let x be your number,
![2(3x) = 80 + x + 10](https://tex.z-dn.net/?f=2%283x%29%20%3D%2080%20%2B%20x%20%2B%2010)
(
![2(3x)](https://tex.z-dn.net/?f=2%283x%29)
is twice the product of 3 and x, and if it exceeds
![x+80](https://tex.z-dn.net/?f=x%2B80)
by 10, then we add 10 to
![x+80](https://tex.z-dn.net/?f=x%2B80)
to make the two sides of the equation equal.)
Now, solve for
![x](https://tex.z-dn.net/?f=x)
.
Answer:
One side is 16. The other is 32.
Step-by-step explanation:
x + 2x + 12 = 60
3x + 12 = 60
3x = 48
x = 16
12 + 16 + 32 = 60
