Answer:

I'm not sure bout what to do so I did this instead.

Step-by-step explanation:

3x + 4x + 19 = 180

7x + 19 = 180

7x + 19 - 19 = 180 - 19

7x = 161

7x ÷ 7 = 161 ÷ 7

x = 23

_________________________

3x + 4x + 19 = 180

3(23) + 4(23) + 19 = 180

69 + 92 + 19 = 180

180 = 180

________________________

3x = ?

3(23) = ?

69 = ?

__________________________

4x + 19 = ?

4(23) + 19 = ?

92 + 19 = ?

111 = ?

prohojiy [21]

Answer:

Total possible ways to select 6 teachers from 34 teacher are ^{34}C_6=1344904.

Step-by-step explanation:

It is given that total number of teachers at a school is 34.

The school director must randomly select 6 teachers to part in a training session.

^nC_r=\frac{n!}{r!(n-r)!}

Where, n is total possible outcomes and r is number of selected outcomes.

Total teachers = 34

Selected teachers =6

Total number of possible ways to select 6 teachers from 34 teacher is

^{34}C_6=\frac{34!}{6!(34-6)!}

^{34}C_6=\frac{34\times 33\times 32\times 31\times 29\times 28!}{6!(28)!}

^{34}C_6=1344904

Therefore total possible ways to select 6 teachers from 34 teacher are ^{34}C_6=1344904.
