- [Multiplication Property of Equality] Multiply 3 on both sides:
![\displaystyle V = \frac{lwh}{3} \rightarro 3V = lwh](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cfrac%7Blwh%7D%7B3%7D%20%5Crightarro%203V%20%3D%20lwh)
- [Division Property of Equality] Divide lw on both sides:
![\displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cfrac%7Blwh%7D%7B3%7D%20%5Crightarrow%20h%20%3D%20%5Cfrac%7B3V%7D%7Blw%7D)
Answer:
x = 3
Explanation:
To simplify this equation, don't worry about the -3, since there is one on both sides. Therefore, they cancel out.
So, 9 + x = 4x
When you plug 3 in for x, it becomes:
9 + 3 = 4 x 3
12 = 12
This equation is true, therefore, x is your answer!
Answer:
-2
Step-by-step explanation:
f(x)=-3x+3
substitute value of f(x) with 9.
9=-3x+3
9-3=-3x
6/-3=x
-2=x
Answer:
4:00 pm
Step-by-step explanation:
To find the time it takes Malik to finish his English essay, let's start by subtracting one hour.
5:30 minus 1 hour is 4:30.
Now, subtract 30 minutes.
4:30 minus 30 minutes is 4:00.
Malik started working on his English essay at 4:00 pm.
Hope that helps.
