Because there are 4 people and all bought the same things you multiple 4(4+1+2)=4x7=28 So the total cost is $28
{-2,-6} because of they are both positive then there is no way you can get 0 by adding and multiplying so they have to be negative
Answer:
3.375 miles
Step-by-step explanation:
Each day Maria walks 0.75 miles, so if she walks for 4.5 days, then 0.75*4.5= 3.375 miles.
Each friend had 2/5 of a bag of peanuts leftovers and they should've bought 2 fewer bags
Which means that there are 2 extra bags
So 2/5 multiplied by the number of friends gives you 2 extra bags
Let x be the number of friends
x(2/5) = 2
2x = 10
x = 5
So 5 friends went to the game.
