Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.
Answer:

Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make
flowers in an hour.
The groups decided to work together. They can make
together in an hour and it takes them
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,
