5(-2a-8) < -9a + 4
Use distributive property on left side:
-10a -40 < -9a + 4
Add 40 to both sides
-10a < -9a + 44
Add 9a to both sides
-a < 44
Multiply both sides by -1 and reverse the inequality sign:
A > -44
Answer: a > -44
9700 is the answer which is correct
5,000,000 + 2000 + 100 + 90
Like that
Limitation: They may be more expensive and time consuming than lab experiments. Limitation: There is no control over extraneous variables that might bias the results. This makes it difficult for another researcher to replicate the study in exactly the same way.
