3p - 5 > 2p + p - 7 solve inequality

3p−5>2p+p−7

1 Simplify 2p+p-7 to 3p-7

3p-5>3p-7

2 Cancel 3p on both sides.

-5>-7

3 Since -5>-7 is always true, there are infinitely many solutions.

It is useful to let a calculator "provide the evidence".the mean of the given numbers is (10 +15 +18 +20 +24)/5 = 17.4. subtract 17.4 from each of the numbers to find the deviation. then find the mean of those numbers (after changing all signs to +).the appropriate choice is   a. 3.92
