Total ratio=9+11=20
number of girls=11/20*400

When you use this formula slope = rise/run like rise over run than you find the slope. rise me y and run means x. So when the line slopes downwards to the right it became negative slope as x increases and when line sloped upward to the right the slope become positive as y decreases.
formula to find slope: slope = rise/run or y/x
Divide both sides by 2 to isolate variable g.
You're left with 6 / 2 < g which equals 3 < g.
Answer:
N=8
Step-by-step explanation:
6N=48
Divide by 6 both sides
6N/6=48/6
N=8
The answer is 8% because each rate (2%) goes up $200, making $1200 at 6% into $1800 at 8%.
Hope this helps!
