Algebra.Com's Answer #116567 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! 49. Victoria weighs 5/7 as much as Mario. Victoria weighs 125 lb. How much does Mario weigh?\r \n" ); document.write( "\n" ); document.write( "Let M = Mario's weight \n" ); document.write( "then from:\"Victoria weighs 5/7 as much as Mario. Victoria weighs 125 lb\" we get: \n" ); document.write( "125 = (5/7)M \n" ); document.write( "To solve, start by multiplying both sides by 7: \n" ); document.write( "875 = 5M \n" ); document.write( "Finally, divide both sides by 5: \n" ); document.write( "175 lbs = M (Mario's weight)\r \n" ); document.write( "\n" ); document.write( "50. Denise's cell phone plan is $29.95 per month plus $.10 per minute for each minute over 300 minutes of call time. Denise's cell phone bill is $99.95. For how many minutes was she billed? \r \n" ); document.write( "\n" ); document.write( "Let m = minutes billed \n" ); document.write( "\"cost\" = \"per month charge\" + \".10 per minute (over 300)\" \n" ); document.write( "99.95 = 29.95 + .10m \n" ); document.write( "70 = .10m \n" ); document.write( "70/.10 = m \n" ); document.write( "700 minutes = m (number of minutes billed) \n" ); document.write( " |
