Answer: 20ways

Step-by-step explanation:

Number of candies = 7

Number of kids = 4

Since each kid must receive at least one candy ;

Therefore number of candies left to ration is

7 - 4 = 3 candies ; among 4 kids.

To share 'n' identical object among 'r' number of individuals can be expressed in the form :

[n+(r-1)Cr-1]

n = 3 ; r = 4

[3+(4-1)C4-1] = 6C3

Recall: nCr = n! / (n-r)!r!

6C3 = 6!/(6-3)!3!

6C3 = 6!/3!3!

= (6 * 5 * 4) / (3 * 2 * 1)

= 120 / 6

= 20ways

When eight times an unknown number is decreased by 208 the result is four times the unknown number.
Naddika [18.5K]
I think

This is your typical algebra question where you are looking for an unknown value given some information. The information can be set up as:
8 - x = 4*(x +3)

Distribute the 4:
8 - x = 4x + 12

Rearrange to get variables on one side:
8 - 12 = 4x + x

Simplifiy:
-4 = 5x

Isolate the variable:
-4/5 = x

Solve:<br> -8r - (-2r-3) = 13<br><br> (if you can give a step by step, that would be great!)
coldgirl [10]

Answer:

r =  -  \frac{5}{3}  = 1 \frac{2}{3}  =  - 1.6

Step-by-step explanation:

- 8r -  ( - 2r - 3) = 13

- 8r + 2r + 3 = 13

- 6r + 3 = 13

- 6r = 13 - 3

- 6r = 10

\boxed{\green{r =  -  \frac{5}{3}  = 1 \frac{2}{3}  =  - 1.6}}
