As d=k t^2 so putting d= 192 for t =8 we get k= 192/(8^2) =3 so k=3
thus d = 3t^2
now if t=6 the d = 3*(6^2) = 3*36
so d = 108
1) 7th grade has more students
I don't get because you did not add a symbol between 110 and 7/16 so i can't tell you.
Answer:
A, H, I, J, E, and F I think. In order from b + 0.17b to 1.17b
Step-by-step explanation:
This kind of doesn't make sense but I just went with my best shot.
Answer:
![x=50](https://tex.z-dn.net/?f=x%3D50)
Step-by-step explanation:
![\frac{x}{5}+15=25\\ \frac{x}{5}+15 -15 =25 - 15 \leftarrow\text { Use the Subtraction Property of Equality}\\](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D%2B15%3D25%5C%5C%20%5Cfrac%7Bx%7D%7B5%7D%2B15%20-15%20%3D25%20-%2015%20%5Cleftarrow%5Ctext%20%7B%20Use%20the%20Subtraction%20Property%20of%20Equality%7D%5C%5C)

<h3>Checking by Substitution:</h3>
![\frac{50}{5} +15=25\\\rightarrow 50/5=10\\10+15=25\\\boxed {25=25}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B5%7D%20%2B15%3D25%5C%5C%5Crightarrow%2050%2F5%3D10%5C%5C10%2B15%3D25%5C%5C%5Cboxed%20%7B25%3D25%7D)
'x = 50' is correct.
