So first we were to told that the sum of 2 numbers add to 19

a+b=19---------(1)

and they subtract to 5

a-b=5-----------(2)

These are two simultaneous equation and can be solved by elimination:

(1) + (2):

(a+b)+(a-b)=19+5

2a=24

a=12

12+b=19

b=7

So the two numbers are 12 and 7

Alice and Bob have two positive integers, x and y respectively, glued to their foreheads, so that each can read the other’s numb

vazorg [7]

Step-by-step explanation: |x − y| = 1, ok lets play as Alice, my number is y, and the bob number is x.

the condition says that x-y = 1 or x-y = -1.

so, if you know x, then y = 1 +y or y = y - 1. so you have two possibilities.

let's see two cases : first, let's suppose there are no code in the conversation. Then the only way of being shure of your number, is if one of them have the lowest positive number, so the other should have the next one. So if Bob have the number one, Alice knows for shure that she has the 2. Bob knows that she has a 2, but that means he could have a 1 or a 3, but when he sees that Alice is shure about her number, he knows that his number is the 1.

the second case is where the conversation may be a sort of code, saying a phrase x times and changing when x = the number of the other person, in this case, bob will have the 201 and alice the 202.

Step-by-step explanation:

x +3 I x⁴ + 0x³ - 6x² + 0x -28 I x³ - 3x² + 3x - 9

x⁴ + 3x³

-3x³ - 6x²

-3x³ - 9x²

3x² + 0x

3x² + 9x

-9x -28

-9x - 27

-1

P(x) =(x +3)* (x³ - 3x² + 3x - 9) + (-1)

One of your company's salesmen estimates he will drive 20,000 miles this year and each of the next two years. As the service man

grigory [225]

Therefore, the total costs for year 1 will be $2,240, for year 2 they will be $2,040, and for year 3 they will be $2,120.

<h3><u /></h3><h3><u>Costs</u></h3>

Given that one of your company's salesmen estimates he will drive 20,000 miles this year and each of the next two years, and as the service manager for the company's fleet of six-cylinder compact automobiles, you are asked to determine the total costs for each of the three years, to determine said cost, the following calculation must be made:

Year 1:
20000 x 0.112 = X
2,240 = X

Year 2:
20000 x 0.102 = X
2,040 = X

Year 3:
20000 x 0.106 = X
2,120 = X

Therefore, the total costs for year 1 will be $2,240, for year 2 they will be $2,040, and for year 3 they will be $2,120.
