81 servings. I found this by making a ratio:
24 c 108 c
------- = -------
18 ser x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81.

I remember doing this back in elementary school. I had a hard time with it too!

In triangle ABC, with right angle B, side AB is 18 units long and side AC is 23 units long. What is the length of side BC,

mihalych1998 [28]

Answer:

BC ≈ 14 units

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

BC² + AB² = AC²

BC² + 18² = 23²

BC² + 324 = 529 ( subtract 324 from both sides )

BC² = 205 ( take square root of both sides )

BC = $\sqrt{205}$ = 14.317.. ≈ 14 units ( to the nearest unit )

Simplify 8+6 over 7 - 3+1 over 2

sergejj [24]

Answer:

First, let's make an expression!

If you meant a different equation..sorry

$\frac{8+6}{7-3} +\frac{1}{2}$

Hope this is what you meant!

$\frac{14}{4} +\frac{1}{2}\\\frac{7}{2} +\frac{1}{2} \\\frac{8}{2} =4$

Hope this helps!

P.S. Stay Safe!
