<em><u>$20 + 3.50 = 23.50, but you have a 6.5% tax, so you would say 23.50 ÷ 6.5 = 361.5384615. but rounded is 361.54</u></em>
Answer:
The answer is 4.
Step-by-step explanation:
This is a basic one-step algebra problem.
We have: 3x = 12.
We would like find what x equals. In order to do that, we must have the x variable on one side of the equals sign, and the rest of the numbers on the other side. In other words, we have to isolate the x variable away from its coefficient.
To do this, we must divide BOTH sides of the equation by 3. This would mean that the 3 on the left side of the equals sign cancels out, totally getting rid of the 3.
Here's what it should look like:
Now, we actually divide both sides now, which should look like this:
This is because 3 divided by 3 is 1, and 12 divided by 3 is 4.
Hence, our solution for x is 4. Hope this helped!
Answer:
The argument is valid
Step-by-step explanation:
The explanation will be given in the image, where we see all propositions and which contains the other, showing that the argument is valid.
Step-by-step explanation:
the volume of :
cone = ⅓π.r².r= ⅓π.r³
cylinder = π.r²r= π.r³
Sphere = 4/3 π.r³
for r = 9 in =>
the volume of:
14. cone = ⅓.π.9³= ⅓π × 729 = 243π in³
15. cylinder = π.9³ = 729π in³
16. Sphere = 4/3 π.9³ = 972π in³
17. the volume ratio among cone, cylinder and Sphere is : ⅓ : 1 : 4/3 =
1 : 3 : 4
