Answer:
It's 20 Pounds btw.
Step-by-step explanation:
7+0.20x = 5+ 0.30x
x- number of additional pounds
10=5+8=13-3 hope it helps!

To solve for x you have to bring the 12 to the other side
How do we do this?
Well if you think about it this is technically what the equation shows

This means to isolate x you can multiply both sides by 12 and that will cancel
from the right side


can be further simplified to...
9
^^^This is the answer
Check:
3/4 = 9/12
3/4 = 3/4

1)Original Equation: V=lwh
Divide by lw: V/w=lw/lw(h)
Answer: h= V/lw
2)Set up the equation as V=lwh
Substitute the variables for numbers: 50=10(2)h
Multiply 10*2: 50=20h
Divide 50each side by 20 to get rid of 20h: 50/20=20/20
H=2.5
The height of the box is 2.5 meters tall.
Given:
A driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m.
To find:
The current location of the driver.
Solution:
In this problem, negative sign is used for downward direction or the distance below the surface of the water.
Initial location = -15 m
Dives down by 6m, it means - 6m, then rises 4m, it means 4 m.
Now, the current location is



Therefore, the correct location of the driver is at -17 m it means her is 17 m below the surface of the water.
