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