where is number 5, 6 and 7
The answer to your question is 8, y=8
Answer:
Step-by-step explanation:
<span>There are 8 girls per 15 campers because 8 divided by 7 boys and 8 girls. The proportion is 8/15. If there are 195 campers, then you are looking for the number of girls, so 8/15 = x/195, where x is the number of girls.
Solve for x.
15x = 8(195)
1560 = 15x
x = 104
104 girls.
Number of boys = y,
195-104=y
y = 91</span>
I got 7 if you are trying to look for the value of x than you multiply the bottom by two to have the y's equal. It should be
3x+2y=25
12x-2y=80
Since the twos mark each other out it would be
3x=25
12x=80
You add the top and bottom so it becomes one like this
15x=105
Divide 15 on both sides and it should give you 7.
X=7
