Answer:
Step-by-step explanation:
L = 3W
Perimeter = 2L + 2W = 2(3W) + 2W = 8W
8W = 65.6 cm
W = 8.2 cm
Answer: 3
Step-by-step explanation: double the 5 and the 4(to have the same denominator as the 8)
Answer:
Equilateral Triangle
(is this what you are asking for?)
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
1. -56
2. say you owe someone 84$, so that's 84$ you don't have, then you give that person 28$. now you only owe them 56$.
