Answer:
7 Hot Dogs
Step-by-step explanation:
Let n stand for nachos and h stand for hot dogs. Setup a system of equations and solve.
n+h = 12
3n +2h = 29
3n+3h = 36
h = 7
To find the mean of a set of numbers you simply add all the numbers then divide by how many numbers you added
113+185+140+219+295 = 952
952/5 = 190.4 (if you need it rounded, just put 190)
Answer:
85
Step-by-step explanation:
68 x 5 = 340
80 x 3 = 240
340+240=580
750-580= 170
170 ÷ 2 ====== 85
