Inspecting Restaurants How many different ways can a city health department inspector visit restaurants in a city with restauran
tankabanditka [31]

Answer:

252 ways

Step-by-step explanation:

The missing details are:

n = 10 --- total restaurants

r = 5 --- restaurants to visit

Required

The number of ways to perform the visitation

The question is an illustration of combination;

So, we have:

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

This gives:

^{10}C_5 = \frac{10!}{(10 - 5)!*5!}

^{10}C_5 = \frac{10!}{5!*5!}

Expand

^{10}C_5 = \frac{10*9*8*7*6*5!}{5!*5*4*3*2*1}

Cancel out 5!

^{10}C_5 = \frac{10*9*8*7*6}{5*4*3*2*1}

^{10}C_5 = \frac{30240}{120}

^{10}C_5 = 252

6x+10=30x+135 solve for "x"
Bezzdna [24]

Answer:

x=-125/24

Step-by-step explanation:

(6x+10)+(-10-30x)=(30x+135)+(-10-30x)

(6x+10)+(-30x-10)=(30x+135)+(-30x-10)

6x+10-30x-10=30x+135-30x-10

6x-30x+10-10=30x-30x+135-10

-24x=125

24x/24=-125/24

x=-125/24
