Answer:
He lost 5 coconuts.
Step-by-step explanation:
When he divides the number left among 3 and 5 people the remainder is 2 in each case so the number that each person gets must be 15 or a multiple of 15.
So if x is the number left when he reaches home, then:
2 = x mod 3 and
2 = x mod 5
where x = 15 + 2 = 17 or 30 + 2 = 32 or 45 + 2 = 47.
But we also must satisfy 3 = x mod 4
If x = 17:
17 mod 4 = 1 so its not 17.
32 mod 4 = 0 so it's not 32.
47 mod 4 = 3 so x = 47.
Therefore the number he lost = 52 - 47 = 5.
Answer:
$466
Step-by-step explanation:
Represent her salary by s. Then the amount spent on rent is s/2.
After spending 168 on her electric and water bills, she had s/2 - 168 dollars left. She spent half of this on her phone bill, leaving her with
s/2 - 168
-------------- dollars.
2
After buying $57 worth of gas, she had
s/2 - 168
-------------- - 57 dollars left, and this came to $92.
2
We must now solve for s.
First, multiply all three terms by 2. We get
s/2 - 168 - 2(57) = 2(92), or
s/2 - 168 - 114 = 184
Simplifying this, we get s/2 = 168 + 114 + 184, or s/2 = 466.
She spent half her salary (that is, half of s) on rent. As seen above, this is $466.

I think this mean that in whatever equation you have, w must be representing -3. Not sure though :)
Answer:
D) 8
Step-by-step explanation:
3x - 7 - 2x + 5 = 6
3x - 2x = 6 + 7 - 5
x = 8
Note: 6 + 7 -5 = 13 -5 = 8
