18 students are 1/10 of the number of seventh graders
First choice.
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
Answer:The team won 15 games
Step-by-step explanation:
Given no of soccer games =50
Ratio of wins to losses =3:7
Let no of wins =
and no of losses =
Now
Dividing both sides by 10
x=5
So no of wins =3x =
=15
We found the answer as 10 parts equals 50
So 3 parts equals 15
The answer is b because the answer is b and the people don’t know how to do it
