n200080 [17]
The dependent value is determine by the value of the independent value. in other words, the dependent value is what you get when you take the independent value and substitute it in the original equation or situation. The relationship is multiplicative because you must first multiply the independent value in the equation where the x is before you can add or subtract to get your answer.<span />

One alloy is 2 parts iron to 3 parts silver and another alloy is 7 parts iron to 3 parts silver. How much of each should be comb
Shalnov [3]
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!

Ahoy there, matey! Our pirate ship had 5/6 of a treasure chest full of gold.
Kisachek [45]

Answer:

1 \frac{5}{24} teasure chests of gold

Step-by-step explanation:

Since this is a problem of adding or subtracting fractions, you will have to do one or the other to solve.  Since the pirates already had \frac{5}{6} of a treasure chest of gold and stole another \frac{3}{8} of a treasure chest to add to their collection, we need to add these two fractions:

\frac{5}{6}+\frac{3}{8}

In order to add or subtract fractions, you need to have a common denominator.  Choosing a common denominator means looking for the lowest common multiple of the two denominators:

6: 6, 12, 18, 24

8: 8, 16, 24

\frac{5}{6}=\frac{20}{24}and\frac{3}{8}=\frac{9}{24}

Add them together:  \frac{20}{24}+\frac{9}{24}=\frac{29}{24}=1\frac{5}{24}
