Preview: ... (-1/8)=19/8<br>Thus x19/8<br>Therefor the solution set is {x19/8}<br>9. CHOICE D<br>solution : <br>Multipling the both sides of the inequality by a negative -7/6 and reversing the sense of the inequality gives:<br>-6/7*(-1/3)=2/7-3*(-1/3)=X<br>Thus x2/7<br>Therefor the solution set is {x2/7}<br>10. The solution set is {xx<-4}<br>solution : <br>Adding 9 to both sides of the inequality gives:<br>6x-9+9<-33+9<br>But 6x-9+9=6x, -33+9=-24<br>Thus 6x<-24<br>Multipling the both sides of the inequality by 1/6 gives:<br>6x*(1/6)<-24*(1/6)<br>But 6x*(1/6)=x, -24*(1/6)=-4<br>Thus x<-4<br>Therefor the solution set is {xx<-4}<br>11. The solution set is {xx>3}<br>solution : <br>Adding (6.5x-17.8) to both sides of the inequality gives:<br>2.4x+17.8+(6.5x-17.8)>44.5-6.5x+(6.5x-17.8)<br>But 2.4x+17.8+(6.5x-17.8)=8.9x, 44.5-6.5x+(6.5x-17.8)=26.7<br>Thus 8.9x>26.7<br>Multipling the both sides of the inequality by 1/8.9 gives:<br>8.9x*(1/8.9)>26.7*(1/8.9)<br>But 8.9x*(1/8.9)=x,26.7*(1/8.9)=3<br>Thus x>3<br>Therefor the solution set is {xx>3}<br>12. The solution set is {x50/7}<br>solution : <br>Adding 1 to both sides of the inequality gives:<br>x/5-1+13/7+1<br>But x/5-1+1=x/5, (3/7)+1=10/7<br>Thus x/510/7<br>Multipling the both sides of the inequality by 5 gives:<br>(x/5)*5(10/7)*5<br>But (x/5)*5=x, (10/7)*5=50/7<br>Thus x50/7<br>Therefor the solution set is {x50/7}<br>13. The solution set is {xx<5}<br>solution : <br>Multipling the both sides of the inequality by 1/5 gives:<br>5(2x-3)*(1/5)<35*(1/5)<br>But5(2x-3)*(1/5)=2x-3, 35*(1/5)= 7<br>Thus 2x-3<7<br>Adding 3 to both sides of the inequality gives:<br>2x-3+3<7+3<br>But 2x-3+3=2x, 7+3=10<br>Thus 2x<10<br>Multipling the both sides of the inequality by1/2 gives:<br>2x*(1/2)<10*(1/2)<br>But2x*(1/2)=x, 10*(1/2=5<br>Thus x<5<br>Therefor the solution set is {xx<5}<br>14. The solution set is {x9} ...
