Solve the problem.

In his algebra class, Rob has scores of 79, 85, 81, and 65 on his first four tests. To get a grade of C, the average of the first five tests must be greater than or equal to 70 and less than 80. Solve an inequality to find the range of scores that Rob can earn on the fifth test to get a C.
◦ x ≥ 40, where x represents Bob's score on the fifth test
◦ 40 ≤ x ≤ 90, where x represents Bob's score on the fifth test
◦ 40 < x < 90, where x represents Bob's score on the fifth test
◦ 40 ≤ x < 90, where x represents Bob's score on the fifth test

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors.
