Answer:
x=8
Step-by-step explanation:
You would set them equal to each other to get 9x-13=6x+11.
You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.
Then move the -13 over so add 13 to both sides to get 3x=24
Then get x by itself so divide by 3 to get x=24/3.
Then that simplified is 8
The answer is A because if you are late for something they charge extra for the money lost
The formula for the volume of a cylinder is pi x radius^2 x height, so after substituting the values, we get 3.14 x 3^2 x 4. First, we find the value of 3^2, which is 9. 3.14 x 9 equals 28.26, so now we have 28.26 x 4, which gives us 113.04. So the volume of the cylinder is 113.04. :)
15 is the answer, I think.
