SOLUTION: I am having problems solving the following inequalities.
Q1) 0.75>-0.5+d
Ans 0.75+0.5 > -0.5 + d +0.5 (adding 0.5 on both sides)
x+4.9 is equal to or less than 0.45

Q1) 0.75>-0.5+d
Ans 0.75+0.5 > -0.5 + d +0.5 ------------->(adding 0.5 on both sides)
1.25 > d ------------->( -0.5 + 0.5 = 0)
d < 1.25
Q2) x+4.9 is equal to or less than 0.45
Ans x+4.9 =< 0.45
x+4.9 - 4.9 =< 0.45 - 4.9 -------->(Subtracting 4.9 from both sides)
x =< - 4.45
Q3) 3.35 is equal to or greater than -4.85+n
Ans 3.35 => -4.85 + n
3.35 + 4.85 => -4.85 +n +4.85------------->(adding 4.85 on both sides)
8.2 => n
n <= 8.2
Q4) 2/5 > t- 7/10
Ans 2/5 + 7/10 > t - 7/10 + 7/10------------->(adding 7/10 on both sides)
2/5 + 7/10 > t
(2*10 + 7*5)/10 > t ------------->(adding fractions)
(20 + 35)/10 > t
55/10 > t
11/2 > t ------------>(simplifying fraction 55/10,
Divide both numenator and demoninator by 5)
t < 11/2
or t < 5.5
