Positive because it equals 7y
1/3=2/6
So he ate 2/6ths of the pizza and now there is 4/6ths left.
He took 1/6ths with him for lunch so 4/6-1/6=3/6
You can simplify 3/6 to 1/2
He was 1/2 of the pizza left.
There are 4 possible outcomes based on 2 types of wash (deluxe wash & other wash) and 2 vacuum uses (with vacuum and no vacuum). Since customers are equally likely to choose between these, we can run a uniform distribution from 1-4, where each represents one outcome. For example, 1 = deluxe+vacuum, 2=deluxe+no vacuum, 3=other wash+vacuum, 4=other wash+no vacuum. Then after running a large number of simulations (ex. 1000), count the number of the desired result (which is the number 2), and divide by the total number. This will give the probability.
SSS (Side, side, side), ASA (Angle, side, angle), SAS (Side, angle, side), AAS (Angle, angle, side), or HL (Hypotenuse, leg). Make sure those factors are congruent with eachother.
