Answer:
<u>There were 12 gold coins in the chest at the start.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
x = Number of gold coins in a chest
1/2x = Number of gold coins taken by the captain
1/4x = Number of gold coins taken by Sally
3 = Number of gold coins left
2. How many coins were in the chest at the start?
Let's write the following equation to solve for x:
1/2x + 1/4x + 3 = x
2x + x + 12 = 4x (Lowest Common Denominator is 4)
4x - 2x - x = 12 (Like terms)
x = 12
<u>There were 12 gold coins in the chest at the start.</u>
Don't quite get the question
The answer to your question is:
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..
Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:
<span><u>3x² - 2x - 5 = 0</u></span>
In terms of the generic quadratic formula:
A = 3
B = -2
C = -5
Plug those into the quadratic formula, and you discover that
<u>x = -1</u>
and
<u>x = ⁵/₃</u>
Answer:
The answer here would actually be 35.
Hope this helps!!
