Answer:
Is there any more to this question?
Step-by-step explanation:
Assuming that the triangle is isoceles, the answer should be 30.
Each piece of rope will be 7 meters
3/15=2/n
Multiply up and down
3*n, 15*2= 3n and 30
Divide by 3 for 3n and 30
3n/3=30/3
n=10
Check answer by using substitution method
3/15=2/n
3/15=2/10
Reduce by 3 for 3/15, Reduce by 2 for 2/10
3/15=1/5
2/10= 1/5
Answer is n=10- G
Rounded would be $13.89.
0.07 * 12.98 = 0.9086 and add that to 12.89 :)
