Answer:
x = -4/5
Step-by-step explanation:
(5x - 2)2 = 10
2(5x - 2) = 10
2 * 5x = 10x
2 * -2 = -4
5x - 4 = 10x
+4 +4
5x = 10x + 4
-10x -10x
-5x = 4

Answer:
n < 5
Step-by-step explanation:

3n/3 < 15/3
n < 3*5/3
n < 5

It's hard to tell from the way the question is written.
-- If he has 5 pennies, then it doesn't matter how many he lost.
He has five of them.
-- If he has 5 pennies after he lost three of them, then there are
eight now, just like there were before, but he only has 5 of them.
-- If he had 5 pennies before he lost three, then there are still
5 pennies, but he only has two of them.
