Yes, algebra uses abstract symbols to represent concrete elements in the real world.

No, in an algebraic equation, the same variable cannot represent two different unknowns.

Yes, many great mathematicians were also philosophers.

No, An algebraic expression doesn't contains an equal sign, but an algebraic equation does.

No, if the expressions are in the same set. Yes, if they are not. (The same variable can represent two different unknowns in two different algebraic expressions.)

The length of a side of an equilateral triangle is 10 inches. What is the length of an altitude of the triangle?

IrinaK [193]

The altitude of an equilateral triangle with side length $a$ is $\frac{a\sqrt{3}}{2}$ .

So, the length of the altitude is

$10 \cdot \frac{\sqrt{3}}{2}= 5\sqrt{3}$

Answer:

1/15

Step-by-step explanation:

To solve, we first make the denominators equal: 5/15 + 9/15. That would equal 14/15. Now we need to know what fraction is left right? So we can do 15/15 (which was the starting amount) minus 14/15 (what we spent). That would equal 1/15 left for other things :)

Hope that helped ^_^
