Solve the inequality then graph the solution set on real number line.
(2/5x)>7
2(x+7)4>5(x3)

math help plzzz 
Reiny
the easy one first:
2(x+7)4>5(x3)
2x + 14  4 > 5x  15
3x > 25
x < 25/3
for the 1st, I don't know why you put brackets around the left side, since it serves no purpose
did you mean 2/(5x) > 7
or
(2/5)x > 7
I will assume the last case:
mulitply both sides by 5
2x > 35
x > 35/2
