Answer:
7 + 3x ≥ 13
Step-by-step explanation:
The best way to write this is to truly understand what each of the terms mean. The sum means that multiple terms are added together, which means that 7 and 3 times a number will be added together.
Next, the term three times a number just means 3x. So as of now, we have 7 and 3x being added together.
Finally, the term at least 13 means that the 7 + 3x is greater than or equal to 13. Once everything is put together, you get a final inequality of 7 + 3x ≥ 13.
The volume of a pyramid would be the base area times the height.
Given the height and volume we can find the base ares by dividing the volume by the height.
64 / 16 = 4
The base area is 4 square feet
X would be 24
24 divided by 2 - 24 divided by 3 = 4
