The 15.867 pounds of her weight is fat.
It is required to find how many pounds of her weight is fat.
<h3>What is percentage?</h3>
A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given that:
Percent or percentage or %means "per 100" or "out of 100". Therefore
12.3%=12.3/100
So 12.3% of 129 pounds is:
=12.3/100*129
=1586.7/100
=15.867
Therefore, the 15.867 pounds of her weight is fat.

Answer:
3 or
C
Step-by-step explanation:
(45 - 3x)^1/2 = x - 9 Square both sides
45 - 3x = x^2 - 18x + 81 Switch sides
x^2 - 18x + 81 = 45 - 3x Add 3x to both sides
x^2 - 15x + 81 = 45 Subtract 45 from both sides
x^2 - 15x + 36 = 0 Factor
(x - 12)(x - 3) =0
The answers are
x = 12
x = 3
Now the question asks which is extraneous. The answer will be which ever number won't solve the original equation. Looking at it right now, both look OK.
(45 - 3*12)^1/2 = 12 - 9
(45 - 36)^1/2 = 3
(9)^1/2 = 3
So 12 is a proper solution.
What about 3?
(45 - 3*3)^1/2 = 12 - 3
(45 - 9)^1/2 = 9
36^1/2 = 9
6 does not = 9
The extraneous solution is x = 3
Answer:
DE=6
Step-by-step explanation:
DE+EF=DF
9x-12+x+10=18
10x-2=18
10x=18+2
x=20/2=10
DE=9x-12 ⇒ 9(2)-12=18-12=6
DE=6

Answer:
y=3x-2 (d)
Step-by-step explanation:
First, we need to look at the y-intercept, we can see that when x = 0, y= -2. So then our equation has to be y=mx+b, and b is -2. next we find our slope, we can see that we go up by 3, then over 1, so our slope is 3/1 or 3. so the final equation is y=3x-2.
Hope this helps!
