\frac{9}{x}  =  \frac{4}{5}
dividing both sides by 9
\frac{1}{x}  =  \frac{4}{5  \times 9}
rasing both sides to the power of -1
x =  \frac{5 \times 9}{4}  =  \frac{45}{4}

Answer:

84

Step-by-step explanation:

x = number of girls

The total for boys is 2x * 81 and for girls it would be 90x

Therefore, the equation goes like this:

2x * 81 + 90x

Then simplify, and set to equal 3x...

3x = 252

Which is the same as

x = 84

What’s the answer too this problem?
guapka [62]

Think about the rule when multiplying powers together.

When multiplying two powers that have the

same base, simply add their exponents.

In this problem, each power has a base

of <em>a</em> and our exponents are <em>m </em>and <em>n</em>.

So adding these exponents together, we have a^m + n.
