You volunteer to help drive children at a charity event to the zoo, but you can fit only 7 of the 18 children present in your va
yulyashka [42]

The answer is 19,448 different groups, using the formula from permutation and combinations C (n, r) = (n!) / (r! (n-r)!) which calculates the number of times where r objects can be chosen from n object.

So,

C (17,7) = (17!) / (7! *(17-7)!)

C (17,7) = (17!) / (7! *10!)

C (17,7) = (17*16*15*14*13*12*11*10!) / (7! *10!) then eliminate 10!

C (17,7) = (17*16*15*14*13*12*11) / (7*6*5*4*3*2*1) = (98017920)(5040)

C (17,7) = 19,448 different groups

I need help on this please can someone help me with this

Answer:

C. 11

Step-by-step explanation:

First, find the value of "x" by solving the first equation. You need to move every other number to the other side of "x". When you move a number, you have to do the opposite operation to both sides.

5x + 6 = 10     The opposite of +6 is -6.

5x + 6 - 6 = 10 - 6     Subtract 6 from both sides

5x = 10 - 6       The "6" on the left cancelled out. Simplify the right side

5x = 4          The opposite of multiply by 5 is divide by 5

5x/5 = 4/5           Divide both sides by 5

x = 4/5           Value of "x"

Substitute the value of "x", which is 4/5, in the "x" for the second equation.

10x + 3

= 10(4/5) + 3             Multiply 10 and 4/5

= \frac{10*4}{5} + 3        Combine into the numerator

= \frac{40}{5} + 3         Divide the top by the bottom

= 8 + 3             Add

= 11                  Value of second equation

Therefore the value of 10x + 3 is 11.
