Does anyone know how to do 9 and 10 ???
I am Lyosha [343]
9.2x-9<7
add 9 to both sides, 2x<16
divide both sides by 2, x<8
A.

10.n<5
-4n+11>-9 Subtract 11 from both sides
-4n>-20 then, divide both sides by -4
In these greather than less than equations, when you divide a negative by another negative, you must flip the sign 
so that would be, n<5

Solve for x.<br><br> x^3=8/125<br><br> Enter your answer in the box as a fraction in simplest form.
Dahasolnce [82]
First you divide 8 by 125, with a new equation of:
x^3=0.064
You then take the cube root of 0.064, which happens to be 0.4
x=0.4
To make sure you can do 0.4*0.4*0.4.
