Algebra.Com's Answer #103957 by Fruglemiester1234(13)![]() ![]() ![]() You can put this solution on YOUR website! The hardest part about these problems is getting from words to numbers. \r \n" ); document.write( "\n" ); document.write( "15 > x - 7... is the equation I get. The phrase \"15 is\" tells me automatically to put \"15=\" no exceptions...well in this case the = sign is the greater than sign(>). And when they say \" a number\" you can just put in any old letter, I like x.\r \n" ); document.write( "\n" ); document.write( "Add 7 to both sides. you get:\r \n" ); document.write( "\n" ); document.write( "......22 > x \r \n" ); document.write( "\n" ); document.write( "x + 11 <= 9... is what I get for the second problem( <= is less than or equal to). Again I see that word \"is\", \"is\" always acts as the = sign (or >, <, <=).\r \n" ); document.write( "\n" ); document.write( "Subtract 11 from both sides. You get:\r \n" ); document.write( "\n" ); document.write( ".......x <= -2\r \n" ); document.write( "\n" ); document.write( "Some basic rules to follow when working with word problems: \n" ); document.write( "...\"A number\" = x \n" ); document.write( "...\"is\" = (=, <, >, >=) \n" ); document.write( " |
