Answer:

\fbox{27}

Step-by-step explanation:

4x+3=3x+9\\4x+3-3=3x+9-3\\4x=3x+6\\4x-3x=3x-3x+6\\x=6

Plug in the 6 to the equations. Since B is the midpoint of AC, then both should be equal once plugged in [and solved].

4(6)+3\\= 27\\3(6)+9\\= 27\\\\\fbox{27}

c+b=7
5c+45b=195

c+b=7 --> c=7-b
5c+45b=195

5(7-b)+45b=195
35-5b+45b=195
35+40b=195
40b=160
b=4

How many ways can a dance instructor send 4 of her 11 students to a summer dance program?
Sedaia [141]

Answer:

d) 330

Step-by-step explanation:

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is  C(11 , 4)

That is 11_{C_{4} } ways

by using formula n_{C_{r} } = \frac{n!}{(n-r)!r!}

now simplification

11_{C_{4} } = \frac{11!}{(11-4)!4!}

      = \frac{11X10X9X8X7!}{(7!)4X3X2X1}

after cancelling 7! and on simplification

   = \frac{11X10X9X8}{4X3X2X1}

after cancellation we get 330 ways

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330
