Answer:
18y(2)-9y-2
Step-by-step explanation:
18y(2)-12y+3y-2
18y(2)-9y-2
If you work out the fraction of 1600 that 640 you can apply this to the number of 6s, that she based this off of.
640÷1600=0.4
To calculate the number of times she rolled the dice you do 8÷0.4=20.
Therefore she rolled the cube 20 times to get 8 6s.
