Answer:

106 km / hour

Step-by-step explanation:

Givens

Total time: 6 hours

Total distance: 1356 km

First bus rate: r

Second bus rate: r - 14

Formula

d = r * t

Solution

r*6 + (r - 14)*6 = 1356             Remove the brackets

6*r + 6*r - 84 = 1356              Add like terms

12r - 84 = 1356                       Add 84 to both sides

12r + 84 - 84 = 1356-84         Combine

12r = 1272                              Divide by 12

r = 1272/12                              

r = 106 km/hr

To adopt a dog from an animal shelter, you must pay $80 for vaccinations, $65 to spay or neuter the dog, and $50 for a wellness
Leya [2.2K]

The equation with (x) in dogs and (y) in dollars is  y=195x

First, you must set up your equation.

y=80x+65x+50x

Then, you must add like terms to simplify the equation

y=195x

A series contains 18 numbers and has a sum of 4,185. The last number of the series is 275. What is the first number?
N76 [4]
If the series is made up of numbers in an arithmetic progression, you have

\displaystyle\sum_{n=1}^{18}a_n=\sum_{n=1}^{18}(a_1+(n-1)d)=18a_1+153d=4185

where a_1 is the first term and d is the common difference between terms.

Since the last term in the series is a_{18}=275, you have

a_{18}=a_1+(18-1)d\implies a_1+17d=275

Solve the system

\begin{cases}18a_1+153d=4185\\a_1+17d=275\end{cases}

and you'll find that the first term is a_1=190 (with d=5).
