When you are on the moon, your mass is 6% of your original weight. 100 divided by 16.6 = 6.024096385542. so orig. M\16.6 = M on moon
You start with 80 and ADD 10 each week
----> 80 + 10x
Your brother starts with 275 and SUBTRACTS 15 each week
---> 275 - 15x
Set expressions equal to find out when you have same amount as your brother.
80 +10x = 275 -15x
Add 15x to both sides
80 +25x = 275
Subtract 80 from both sides
25x = 195
Divide by 25
x = 7.8 (Round up to 8)
This means in 8 weeks you will have caught up and if fact have more money than your brother.
Since you save 10 per week, in 8 weeks the Total saved = 10*8 = 80
Asset is what I think it is
Answer:
We have to prove,
(A \ B) ∪ ( B \ A ) = (A U B) \ (B ∩ A).
Suppose,
x ∈ (A \ B) ∪ ( B \ A ), where x is an arbitrary,
⇒ x ∈ A \ B or x ∈ B \ A
⇒ x ∈ A and x ∉ B or x ∈ B and x ∉ A
⇒ x ∈ A or x ∈ B and x ∉ B and x ∉ A
⇒ x ∈ A ∪ B and x ∉ B ∩ A
⇒ x ∈ ( A ∪ B ) \ ( B ∩ A )
Conversely,
Suppose,
y ∈ ( A ∪ B ) \ ( B ∩ A ), where, y is an arbitrary.
⇒ y ∈ A ∪ B and x ∉ B ∩ A
⇒ y ∈ A or y ∈ B and y ∉ B or y ∉ A
⇒ y ∈ A and y ∉ B or y ∈ B and y ∉ A
⇒ y ∈ A \ B or y ∈ B \ A
⇒ y ∈ ( A \ B ) ∪ ( B \ A )
Hence, proved......
Answer:
No solution, this is not an arithmetic sequence
Step-by-step explanation:
An arithmetic sequence is the same number being added over and over. This is not the case.
