2x(-7)^2-9 = 2x49-9=98-9=89 maybe
Answer:
20100
Step-by-step explanation:
There are 200 numbers in this addition problem. To add this, we can do 1 + 200, 2 + 199, 3 + 198 and so on. All of these pairs have a sum of 201 and since there are 200 / 2 = 100 pairs the answer is 201 * 100 = 20100.
H + c = 456
c = 3h
h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold
c = 3h
c = 3(114)
c = 342......cheeseburgers sold
