Step-by-step explanation:
-23/3 + (-11/2) + 35/4
<em>Find a common denominator (12).</em>
-92/12 + (-66/12) + 105/12
<em>Reform the equation to have this as a single fraction.</em>
(-92 + (-66) + 105)/12
<em>Subtract 66 from -92 to get -158.</em>
(-158 + 105)/12

X=invested at 10%12000-x=invested at 15% .10x+ (.15)(12000-x)=1440 ;; 12% of the total amount is 12% of $12000. .10x + 1800-.15x=1440
-0.05x=-360x=7200 12000-x=4800 $7200 at 10%=$720$4800 at 15%=$720 That is $12000 earning $1440, and that is 12%
