set x as the number of sessions remaining

lilai3 · Answer

okay. then...?

unklerhaukus · Answer

[goal] ≤ [hours already practiced]+[hours of practice remaining]
[goal] ≤ [hours already practiced]+[hours per session]×[number sessions remaining]

lilai3 · Answer

wait.. what? this is confusing..

lilai3 · Answer

her goal is 12 hours?

unklerhaukus · Answer

yes

lilai3 · Answer

$$12\le 3+(12-3)$$

unklerhaukus · Answer

[option] [,]     $\to$       ≤

lilai3 · Answer

wait what? where's option?

unklerhaukus · Answer

[option/alt]

lilai3 · Answer

no. where is option? is it on the keyboard, or right-click on the mouse or what? you are making me confused...

unklerhaukus · Answer

my keyboard has a key with  'alt' and 'option'    on it

lilai3 · Answer

oh, i see....okay, any way is my equation right? please scroll up to see my equation.

unklerhaukus · Answer

$12≤3+$[hours per session]$×$[number sessions remaining]

lilai3 · Answer

$$12\le3+12\times(12-3)$$

right?

unklerhaukus · Answer

nope,

lilai3 · Answer

i don't get it then. because that is what you told me to do.

unklerhaukus · Answer

'She practices for three-fourths of an hour each session. '

[hours per session] =  3/4

[number sessions remaining] = x

lilai3 · Answer

oh...isn't that just 45 minutes?
