Answer:
No you can't.
Step-by-step explanation:
4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)
Answer:
C
Step-by-step explanation:
First, Karen only has $20, so her spending cannot go over this amount. That would would that she can spend exactly $20 or less than $20. We need a equal to/less than sign before $20, so answer choices A and D can easily be eliminated.
Next, the admission costs $6. This is a cost that Karen will only pay one time, so it's represented by + 6. This eliminates B, but I will still explain why C is completely correct.
Each ride costs $2, meaning that we can represent this amount with 2x, which is just $2 times the amount of rides she will go on. When fully written out, the inequality is 2x + 6 (less than or equal to sign) 20, making C the correct answer.
Let's assume the pool is a rectangular block
If you know the length width and depth (or height) of the pool, then you can find the volume.
For example
length = 30 feet
width = 10 feet
depth = 8 feet
volume = length*width*depth = 30*10*8 = 300*8 = 2400 cubic feet
This is assuming that the depth stays the same throughout the pool. Though some pools (or most?) have the depth gradually get deeper as you move toward the deep-end. To keep things simple however, the assumption is that the bottom is completely flat and it doesn't gradually get deeper.
