Three times a number plus 16
DochEvi [55]
To solve this, we simply need to break down the words and turn each part into an equation.

"Three times"
This shows that we will be multiplying 3 and something.
3*

"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n

"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16

Using the logic above, we can see that the equation to represent this is 3n+16.

Jeff gave 1/4 of a sum of money to his wife. Then he divided the remainder equally among his 4 children.
Semenov [28]

Answer:

A) The fraction of sum of money did each child receive is \frac{3 x}{16}

B) The sum of money did Jeff have $ 3200

Step-by-step explanation:

Given as :

Let The sum of money did Jeff have = $ x

The fraction of money did Jeff's wife get = \frac{1}{4} of $ x

The remaining money Jeff will have = $ x - \frac{1}{4} of $ x

I.e The remaining money Jeff will have = \frac{4 x - x}{4}

                                                                = \frac{3 x}{4}

A ) The remaining amount of money is divided equally among 4 children

So, The fraction of sum of money did each child receive = \frac{\frac{3 x}{4}}{4}

I.e The fraction of sum of money did each child receive =  \frac{3 x}{16}

B ) If each child will receive $ 600

∴,  \frac{3 x}{16} = $ 600

Or, 3 x = $ 600 × 16

Or, 3 x = $ 9600

∴    x = \frac{9600}{3}

I.e  x = $ 3200

So, The sum of money did Jeff have $ 3200  

Hence ,

A) The fraction of sum of money did each child receive is \frac{3 x}{16}

B) The sum of money did Jeff have $ 3200   Answer
