Margret is inviting 3 friends to a party. If each friend will get 8 cookies and each box has 6 cookies, how many boxes does Marg
Alisiya [41]

Answer:

Margret need to get 4 boxes of cookies.

Step-by-step explanation:

Total friends = 3

Cookies each friend will get = 8

Each box has cookies = 6 cookies

How many boxes does Margret need to get?

Total cookies will be= Total friends x Cookies each friend will get

Total cookies will be= 3 x 8 = 24

If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes

Number of boxes = Total cookies/ number of cookies in one box

Number of boxes = 24/6

Number of boxes  = 4

So, Margret need to get 4 boxes of cookies.

PLEASE HELP !!!!!!!!!! Jonas used linear combination to solve the system of equations shown. He did so by multiplying the first
OverLord2011 [107]
This question is worded slightly strangely but I believe I understand it. 
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
Then you can subtract 4x on the top by 4x on the bottom to eliminate it.

Sum of deviations

= |5- 12| + |8 – 12| + |10- 12| + |15- 12| + |22-12|

= 7+4+2+ 3+ 10
