And I have two more problems and that's it.The next one is solve the equation for x, 6x minus 18=4x+8 and I don't know where to begin.And the last one is solve the equation for n,-55 minus 4n=13,there is another problem that I don't know where to begin can you please help me, thank you very much. \n" ); document.write( "

If a=0.65 and b=1.28 and c= -5/2,evaluate -a(-b)+c. \n" ); document.write( "-0.65(-1.28)+(-5/2) \n" ); document.write( "=0.832-(5/2) \n" ); document.write( "=0.832-2.5 \n" ); document.write( "=-1.668 \n" ); document.write( "------------------------ \n" ); document.write( "The next one is solve the equation for x, 6x minus 18=4x+8 \n" ); document.write( "6x-18=4x+8 \n" ); document.write( "Subtract 4x from both sides to get: \n" ); document.write( "2x-18=8 \n" ); document.write( "Add 18 to both sides to get: \n" ); document.write( "2x=26 \n" ); document.write( "Divide both sides by 2 to get: \n" ); document.write( "x=13 \n" ); document.write( "-------------\r \n" ); document.write( "\n" ); document.write( "And the last one is solve the equation for n,-55 minus 4n=13 \n" ); document.write( "-55-4n=13 \n" ); document.write( "Add 55 to both sides to get: \n" ); document.write( "-4n=42 \n" ); document.write( "Divide both sides by -4 to get: \n" ); document.write( "n=-10.5 \n" ); document.write( "-------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
