19 * 42 + 19 * 58 =
19(42 + 58) =
19 * 100 =
1900
First one; substitute x into the equation and see if the result equal y in the coordinate
The answer is a medium Pizza of 12 inches radius.
The formula for finding the area of a square is pir^2(sorry but my phone won’t let me write pi in its symbol form). If we substitute 3 for pi, then that would the 3r^2. Then we would substitute the potential answer choices until we reach one that is closest to 400 in^2. For the small pizza, that would be 9*9*3, which is also 243 inches square. For the medium pizza, that would be 12*12*3, which is also 432 inches square. Finally, for the large pizza it is 15*15*3, which is 675. Therefore, the medium pizza has an area closest to inches square.
Answer:
1/2
Step-by-step explanation:
2 red marbles, 3 blue marbles, and 1 green marble= 6 marbles
P( blue) = blue /total
= 3 /6
= 1/2
B) No. the x values and the y values do not all increase by the same number
