It's undefined, but I think you spelled it wrong.
Since my name is in this question, I'll answer it :)
Answer:
Yes, she's right.
Step-by-step explanation:
2/8 is simplified to 1/4. Between 1 and 1/2, it is 1/4. So yes, I (Candice) was right. :)
Answer:
x=16
Step-by-step explanation:
y = 1/2 x -3
Let y =5
5 = 1/2 x -3
Add 3 to each side
5+3 = 1/2 x -3+3
8 = 1/2x
Multiply each side by 2
8*2 = 1/2x*2
16 =x
Letter D
1-sin^2(x) = cos^2(x)
= sin^2(x)/cos^2(x)
= tan^2(x)
Let, the number be "a"
Now, according to the question,
![\frac{a}{3} - 4=20](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7B3%7D%20-%204%3D20%20)
![\frac{a-12}{3} =20](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba-12%7D%7B3%7D%20%3D20%20)
![a-12 =20*3](https://tex.z-dn.net/?f=a-12%20%3D20%2A3%20)
![a-12=60](https://tex.z-dn.net/?f=a-12%3D60)
![a = 72](https://tex.z-dn.net/?f=a%20%3D%2072)
So, the number is 72
