4*20 is 80. 2*5 is 10.
There would need to be 90 meatballs.
The problem gives you the time in hours, but you're looking for your answer in minutes so change 1/10 of an hour to minutes first. To do this, multiply 1/10 by 60 to get 6 minutes. Since there are 4 quarters in a whole, multiply 6*4. It would take her 24 minutes to drink the whole shake
Well, first off 1 hr =60 minutes. 60 min - 45 min = 15 minutes extra. what is one hour before 4:15? 3:15! Add the subtracted 15 minutes to get 3:30... Hope this helps
The answer is -4,0 4,8 because u would solve for one variable in one of the equations and then substitute the result into the other
