Answer:
The answer is 3 inch
Step-by-step explanation:
To start off, the equation you want to use the formula V=whl
Next, you simply plug in the values you already know, so you have 450=w*20*7.5
After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.
Answer:
0.986
Step-by-step explanation:
2.5 times 0.986=2.465
First you expand the brackets:
3x - 27 = 30
And then you can solve:
3x - 27 = 30
+ 27
3x = 57
÷ 3
x = 19
Hope this helps!
