Answer:
87% full
Step-by-step explanation:
<u>To find the solution:</u>
- Use the equation p·x=y where x = 13,920 and y = 16,000
- Since you are trying to find the percent, divide both sides of the equation by 13,920. p · 13,920(÷13,920) = 16,000(÷13,920)
- The step above cancels out the 13,920 leaving you with the answer. p=0.87
- 0.87 = 87%
Answer:
x <3
Step-by-step explanation:
13x-4 < 12x-1
Subtract 12x from each side
13x-12x-4 < 12x-12x-1
x-4 <-1
Add 4 to each side
x-4+4<-1+4
x <3
