she would need, hours (maybe minutes) and if she was doing daily or weekly amount of time.
Step-by-step explanation:
yes because it would give you numbers that you could then use to make some sort of chart to better understand your data
3p+2h=195
p + 15 = h
3p + 2(p + 15) = 195
3p + 2p + 30 = 195
5p = 165 (combine like terms and isolate your variable)
p = 33
33 + 15 = 48 (plug 33 into your original second equation)
ANSWER: 33 pretzels and 48 hotdogs
**You can plug these into your original (first) equation to check your answer
Answer:
p = 10.44
Step-by-step explanation:
There is no solution. If the question was 81p / 9 = 94, it could be done.
The way it is written the ps cancel out and you get 9 = 94 which is impossible.
But let's assume you meant
81p / 9 = 94
Then you get 9p = 94 Divide both sides by 9
81p/9 = 94
9p = 94 Divide both sides by 9
9p/9 = 94/9
p = 10.44
