The weight of fat is 23.76 pounds.
Step-by-step explanation:
Given,
Fat percentage = 16.5%
Total weigh = 144 pounds
Weight of fat = ![16.5\% \ of\ total\ weight\\](https://tex.z-dn.net/?f=16.5%5C%25%20%5C%20of%5C%20total%5C%20weight%5C%5C)
![Weight\ of\ fat=\frac{16.5}{100}*144\\Weight\ of\ fat=\frac{2376}{100}\\Weight\ of\ fat= 23.76\ pounds](https://tex.z-dn.net/?f=Weight%5C%20of%5C%20fat%3D%5Cfrac%7B16.5%7D%7B100%7D%2A144%5C%5CWeight%5C%20of%5C%20fat%3D%5Cfrac%7B2376%7D%7B100%7D%5C%5CWeight%5C%20of%5C%20fat%3D%2023.76%5C%20pounds)
The weight of fat is 23.76 pounds.

Hint: There are several ways to proceed in this kind of problems, but usually the simplest and the one that will yield the most success on average is substituting.
Look at y variable and the expressions to which it is equal; substitute the easier-looking one in the more complicated.
Applying this, we get: 2x+2=x^2+3x-4
x^2+x-6=0.
Solving this equation of 2nd degree, we have a=1, b=1, c=-6 and we get Δ=25 and the solutions are -3 and 2. Hence, we get that the only possible values for x are -3 and 2.
To get the solutions, we have to also find the corresponding y-values:
For x=-3, y=2x+2=-4. For x=2, y=6.
Hence, the 2 pairs of solutions are: (-3,-4) and (2,6)
Let x=total crew number
![\frac{x}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B8%7D)
= 0.6666..
cross multiply
![\frac{8}{0.666}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B0.666%7D%20%20)
= x
x=12
12-8 = 4
So there are 4 women in the crew
Answer:
(35-2- is the correct answer you can believe me
Answer:
$66
Step-by-step explanation:
from the question,
let cost for one purse = X
let cost for one necklace = Y
from the question,
2Y+ 3X= 208.50-------(1)
Y + X = 91.50----------(2)×3
3Y + 3X =274.5--------(3)
subtract equation equation 2 from 3
3Y + 3X = 274.50
2Y + 3X =208.50
Y = 66
cost of one necklace= $66
