Answer:
1/5
Step-by-step explanation:
To find how much of a meter she used per bow, divide 4 by 20, since she used 4 meters for 20 bows:
4/20
= 0.2 or 1/5
So, she used 1/5 of a meter for each bow

Answer:
E=2.8 m-40
Step-by-step explanation:
We konw that 30°E=25°M and 310°E=125°M
so if we want to write an ecuation that linearly relates E with M, we can use the formula of the line that crosses two points:
Y-y1= (y2-y1)/(x2-x1)*(X-x1)
In thts case:
- y1= E1= 30
- y2= E2=310
- x1= M1= 25
- x2=M2=125
so
E-E1= (E2-E1)/(M2-M1)* (M-M1)
E-30 = (310-30)/(125-25)*(M-25)
E-30 =280/100 *(M-25)
E-30 =2.8 M- 280*25/100
E-30 =2.8 M-70
E= 2.8 M-70+30
E=2.8 M-40
Good luck!
