D

Session

D) 111

Step-by-Step Explanation: In order to determine how many slices of sausage pizza were sold, you have to find out how many pepperoni and cheese pizza slices were sold as well. It says that 117 slices of pepperoni pizza were sold, so we don’t have to figure that one out. To find the cheese pizza slices that were sold, you have to subtract 117-34 because it says how many more pepperoni slices were sold than the cheese ones. The cheese pizza slices that were sold are 83 slices. So, to find the sausage pizza slices that were sold, you’re going to add 83 and 28, since the 28 more slices of sausage pizza was sold than the cheese. 83+28=111.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
