4x+6 is produced each day.
So in 12 days the expression is 12(4x+6)
Solve and you get 48x+72.
Answer:
<h2><u><em>
x = -2.27272727273</em></u></h2><h2><u><em>
in fraction</em></u></h2><h2><u><em>
x = -25/11</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
Solve for X
6x+60x+150=0
66x = -150
x = -150 : 66
<u><em>x = -2.27272727273</em></u>
<u><em>in fraction</em></u>
<u><em>x = -25/11</em></u>
Answer:
Step-by-step explanation:
90 by 20%
10%=9
20%=18
90-18=62
