Answer:
75 %
Step-by-step explanation:
Total = 60
Boys = 15
Girls = 60-15
=> 45 girls
<u><em>Percentage of Girls:</em></u>
=> ![\frac{45}{60} * 100](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B60%7D%20%2A%20100)
=> ![\frac{450}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B450%7D%7B6%7D)
=> 75 %
These questions can be daunting at first, but they're pretty simple to solve.
First, we need to establish a common denominator. We have 2 / 3, 1 / 4, and
-4 / 3. The least common denominator we can get is by multiplying 4 and 3 together to get 12. So we will change the denominator as follows;
2 / 3, 1 / 4, -4 / 3 = 8 / 12, 3 / 12, -16 / 12
Now we can put these back into the equation.
8/12x + 3/12 = -16/12
8x + 3 = -16
It's simple math from here on out, but I'll show the process. What we can basically do now is take away the denominator because it doesn't matter now that it's common.
Subtract 3 from both sides. Now we have 8x = -19
Dividing by 8 on both sides of the equation will get you your answer.
x = -19/8
Hope this helps!
Because M is the midpoint of AB, then AM and MB are equal distances. And because a segment can be written as the sum of its pieces, AM + MB = AB.
So,
AM + MB = AB <--- distance of a segment is the sum of its pieces
AM + AM = AB <--- M is the midpoint, so AM = MB
3x + 3 + 3x + 3 = 8x - 6 <--- substituting known amounts that were given
6x + 6 = 8x - 6 <--- collect like terms on the left side
6x = 8x - 12 <--- subtract 6 on both sides
-2x = -12 <--- subtract 8x on both sides
x = 6 <--- divide both sides by -2
Because x = 6, we put it back into AM. 3(6) + 3 = 18 + 3 = 21
Thus, AM is 21 units.
Hey there, 8 birdies in an 18 hole is 8/18, 8/18 simplified is 4/9, 4/9*45=20. Therefore, the answer is 20 birdies.
