Answer:
x < -3/4 OR x>16/5
Step-by-step explanation:
5x – 4 > 12 OR 12x+5 < -4
Solve the parts separately and then put back together
5x – 4 > 12
Add 4 to each side
5x-4+4>12+4
5x >16
Divide each side by 5
5x/5>16/5
x > 16/5
12x+5 < -4
Subtract 5 from each side
12x+5-5<-4-5
12x<-9
Divide each side by 12
12x<-9/12
x <-3/4
Put back together
x < -3/4 OR x>16/5
I'm attaching the solution.. feel free to ask if you have questions.. I basically did long division. Hope this helps.
General formula :
V = pi x radius squared x height
41.5 = pi x 4 x h
41.5 = 4pi x h
41.5/4pi = h
3.302465069 = h
