Set up an equation. Since the ratio is 3:4 male:female, it would be 3m=4f. Since you know that 3m=18, solve for m and plug it into the 3m=4f equation to get the number of females! Don't forget that the number of females is 4f not just f!
Answer by JKismyhusbandbae: 
Explanation: The slope is 5/3 but it every-time it goes up by 3.
We are given :
The cost of one adult ticket = a.
The cost of one child ticket = c.
<u>Roy buys</u>
6 adult tickets and 2 child tickets.
Total amount = $66.
Therefore, first equation for Roy total amount would be
<em>6a +2c = 66 --------------------(1)</em>
<u>Elisa buys</u>
5 adult tickets and 4 child tickets.
Total amount = $62.
Therefore, second equation for Elisa total amount would be
<em>5a +4c = 62 --------------------(1).</em>
Therefore,
<h3>Roy
<u>6</u>a + <u>2</u>c = <u>66</u></h3><h3>
Elisa <u>5</u>a + <u>4</u>c = <u>62.</u></h3>
The answer would be <span> because you are using 12 as the base and 12 x 12 = 144 but hoped this helped :) :D :)</span>
In mathematics there is a rule of exponents where we can "distribute" the powers/exponents in the numerator and denominator of any expression. Therefore, given an expression as 
, the exponent n can be "distributed" as: 
.
In our case, the power, n=11; a=7 and b=4. Thus, the expression 
, can be written as 
.
Thus, out of the given options, option A is the correct option.
