A soccer team has 12 girls and 18 boys. The team is split into groups that have the same ratio of girls to boys as that of the w
hole team. How many girls are in a group that has 12 boys?
1 answer:
Answer: 8 girls
Step-by-step explanation:
The team is split into groups that have the same ratio as the whole team.
This means that every group must obey this ratio:
12 girls : 18 boys
At the lowest form (dividing both sides by 6), the ratio is:
2 : 3
Every group must therefore be in a ratio of; 2 : 3.
In a team group that has 12 boys, the number of girls is:
2 : 3
x : 12
3x = 24
x = 24 / 3
x = 8 girls

(f-g)(x)=2^x-x-1
Step-by-step explanation:
(f+g)(x)=2^x-3x+1-2x
=2^x-5x+1
(f-g)(x)=2^x-3x-1+2x2x
=2^x-x-1
The correct answer is x= -9. Hope this helps!!
