90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
hope this helped
Answer:
You can opt to study the entire population when the population is well defined(Complete sampling frame) and small.
It can eliminate any potential bias occurring through sampling technique, but other than that it is really not justified to consume more resources and time.
-6x-7+8=19 and then add your like terms so it’s -6x+1=19 and then subtract one on both sides so it’s -6x=18 so x=-3
Graphing it out yields the radius of the cylinder is 5 inches.
