Answer: 12/40
Step-by-step explanation:
Basically you gotta add up all of the number of students who are getting each of the food, then you have to put the number of student that want a hamburger. You also have to create the fraction which is 12/40
Decimal=9.03 &
fraction= 9 3/100
For the first questions it is x = -2 then the second one is x = 12 the third is x = 15
5 - 8 would be a negative answer
think of it as a bank account if you $5 in the account and you take away $8, how much would you have after? $-3 so your answer would be -3
and same with -5-(-3)
this would be -2
