The question relates to the total number of pairs of feet ducks and a pigs
are known to have.
<u />
- <u>There are 5 pigs and 10 ducks</u>
Reasons:
The length of the group of ducks and pigs = 40 feet
Number of ducks = Twice the number of pigs
Let <em>x</em> represent the number of pigs, and let <em>y</em> represent the number of ducks, we have;
y = 2 × x
4·x + 2·y = 40
Which gives;
4·x + 2 × (2·x) = 40
8·x = 40
x = 40 ÷ 8 = 5
- The number of pigs, <em>x</em> = 5
y = 2 × x
Therefore;
y = 2 × 5 = 10
- The number of ducks, <em>y</em> = 10

There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
