Answer:
when rolling a die you can end up getting 6 possibilities all together.
the number of even numbers in a die is 3.
therefore in the first throw you have a possibility of getting an even number at 0.5 or 50%.
and in the second throw you have a possibility of getting an even number at 0.5 x 0.5 which is 0.25 or 25%.
Hope this helps.
Hi there! Lily has $31.50 left.
To find our answer we first need to know the amount of money Lily spend.
![10\% \times 35 = 0.1 \times 35 = 3.50](https://tex.z-dn.net/?f=10%5C%25%20%5Ctimes%2035%20%3D%200.1%20%5Ctimes%2035%20%3D%203.50)
Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.
![35 - 3.50 = 31.50](https://tex.z-dn.net/?f=35%20-%203.50%20%3D%2031.50)
Hence, Lily has $31.50 left.

plug 1 in for x and 2 in for y
2x1=2 is 2=2
