<h3>Answer:  15 years old</h3>

=============================================

Explanation:

m = Maggie's age (some positive whole number)

4m = four times her age

4m-7 = seven years younger than 4m = brother's age

Add up her age (m) and her brother's age (4m-7) to get a sum of 68.

m+(4m-7) = 68

5m-7 = 68

5m = 68+7

5m = 75

m = 75/5

m = 15

Maggie is currently 15 years old.

Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.

Their current year ages add to: 15+53 = 68 which confirms the answer.

At a party there is one bottle of coke for every 3 guests, one bottle of sprite for every 6 guests, and one bottle of lift for e
kodGreya [7K]

Answer:

  72 guests

Step-by-step explanation:

We can add up the numbers of bottles per guest, then use that total to find the number of guests from the number of bottles.

<h3>Setup</h3>

Let g represent the number of guests at the party. Then there are ...

  • g/3 bottles of coke
  • g/6 bottles of sprite
  • g/4 bottles of lift

The total number of bottles is ...

  g(1/3 +1/6 +1/4) = 54

<h3>Solution</h3>

Multiplying by the inverse of the coefficient of g, we find its value to be ...

  g(4/12 +2/12 +3/12) = g(9/12) = 54

  g = 54(12/9) = 72

There are 72 guests at the party.

Rita has a debit of $324 how much money does she need so that she doesn't do anything but left with no additional money?
Ilya [14]

Rita has a debit of $324, or she owes 324. Her balance is -324

The additive inverse property states that to find 0, add the inverse of the number

(-324) + (324) = 0

Rita would need to deposit $324.

hope this helps
