1.how do i evaluate log 37.5?
log(37.5) =~ 1.57403 (using a calculator)
---------------
2. How do i evaluate log 0.72
Same as #1
-----------
3. solve the inequality, 10x+1/5-8x+4/6 < less than or equal to 2x-7.
10x+1/5-8x+4/6 <= 2x-7
If you mean
(10x+1)/5 - (8x+4)/6 <= 2x-7
Multiply by 30 to eliminate fractions
6(10x+1) - 5(8x+4) <= 60x - 210
20x - 14 <= 60x - 210
196 <= 40x
40x >= 196
x >= 4.9
