Answer:
<h2>4.5 N</h2>
Step-by-step explanation:
To convert 1 pounds to its meteric unit in weight, we need to first convert it to kilogram. Using the conversion 1pound = 0.453592 kg
Since Weight of a substance = mass of the substance * acceleration due to gravity
W = mg
Given mass = 0.453592kg and g = 9.8m/s²
Weight = 4.4452016 Newtons
1 pounds is therefore closest to 4.5 units metric of weight
Answer:
x=2; y=1
Step-by-step explanation:
Since the triangle is equilateral, which means three sides have the same length.
So we have:4x-y=2x+3y=7

Since 2x+3y=7 and plug in x=2y
we have

and since y=1
x=2
