Step-by-step explanation:

If a and b must be positive integers, what is the largest integer n such that 13a + 18b = n has no solutions?

Answers

Answer:

234

Step-by-step explanation:

By Euclidean Algorithm on 13 and 18, we found that 13(7)+18(−5)=1.

Then we multiply the equation by n, we got  

13(7n)+18(−5n)=n.

Thus 13(7n)+18(−5n)=n always has integer  solution.

However, a and b must be positive integers. So we need to reduce 7n and increase -5n  

to make them positive. Noting that13(18m)=18(13m)∀m∈Z.

⇒13(7n−18m)+18(−5n+13m)=n⋯(1)

Let a=7n−18m and b=−5n+13m.Since a and b are positive integers, we have two inequalities:

7n−18m>0 and −5n+13m>0

⇒5n13<m<7n18⋯(2)

In order to make 13a+18b=n has no solutions,n must be taken to make (2) is impossible.

That means there exists no such integer m lying in the interval (5n13,7n18).

As a consequence, the difference between  

5n13 and 7n18 must not greater than 1.

7n18−5n13≤1⇒n13×18≤1⇒n≤234.

Let’s put the largest candidate n=234 into (2), we get 90<m<91 ⇒ m is not an integer, which is a contradiction!

Therefore the largest integer n to make 13a+18b=n has no positive integer solutions is 234.

A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work at the same rate?​

Answers

Step-by-step explanation:

If 20 labourers=10 days

x labourers = 25 days

10x= 25×20

[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]

Cancelling out by 10 on both sides

[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]

Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

Write formula for f(x) in slope intercept form

Answers

Answer:

f(x) = 1000x + 3000

Step-by-step explanation:

the point (0,3000)

p2 (1,4000)

slope = (y2-y1) / (x2-x1)

= (4000 - 3000) /( 1-0)

slope = 1000 = m

y = mx + b

y=1000x + b

Use one of the points to find b :

3000 = 1000(0) + b

b = 3000

f(x) = 1000x + 3000
