girlover · Answer

Sry can't help any further look up notations tho

texaschic101 · Answer

31.19 + .47x < 48.57 + .36x
.47x - .36x < 48.57 - 31.19
.11x < 17.38
x < 17.38/.11
x < 158

(- infinite sign, 158) -- I think that is the correct interval notation

lol....that makes sense (0,158) because there wouldn't be an infinity sign because there is not supposed to be a negative number...my mistake

texaschic101 · Answer

make sure you put ( ) and not [ ] because there is no equal sign involved
