I'm really stuck on this math problem. I never learned this in school. Can someone please help me out? Thank you

Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
$d= \sqrt{(x2-x1)^2+(y2-y1)^2}$

Pythagorean Theorem:
$a^2+b^2=c^2$

Distance formula is better if you're finding distance between two coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.

I'll work the first one out for you:
x1 y1 x2 y2
(3, 2) & (7, 4)

$d= \sqrt{(7-3)^2+(4-2)^2}$
v
$d= \sqrt{(4)^2+(2)^2}$
v
$d= \sqrt{(16+4}$
v
$d= \sqrt{20}$

There's your answer!

Answer:

102 mg

Step-by-step explanation:

Let's convert 28 pounds to kgs.

Since 1 kg = 2.2 pounds, we can find:

$\frac{1Kg}{2.2Pounds}=\frac{xKg}{28Pounds}\\1*28=2.2x\\28=2.2x\\x=\frac{28}{2.2}\\x=12.73$
