Algebra.Com's Answer #105740 by stanbon(75887) ![]() You can put this solution on YOUR website! 1. A stack of nickels and dimes is worth $2.55. Find the number of nickels if the number of dimes is 12 less than twice the number of nickels. \n" ); document.write( "Quantity equations:d = 2n -12 \n" ); document.write( "Value equation: 5n + 10d = 255 \n" ); document.write( "--------- \n" ); document.write( "Rearrange: \n" ); document.write( "2n - d = 12 \n" ); document.write( "n + 2d = 51 \n" ); document.write( "Use any method to solve for n and for d. \n" ); document.write( "============================================= \n" ); document.write( "2. Raul is 5 years older than twice Carols age. The sum of their age is 101. How old is Carols? \n" ); document.write( "Age equation: R + C = 101 \n" ); document.write( "Age equation: R = 2C + 5 \n" ); document.write( "--------------- \n" ); document.write( "Rearrange: \n" ); document.write( "R + C = 101 \n" ); document.write( "R - 2C = 5 \n" ); document.write( "Use any method to solve for R and for C \n" ); document.write( "==================== \n" ); document.write( "3. The perimeter of a rectangle is 3 inches less than twice the width. If the perimeter is 18 inches, find the width. \n" ); document.write( "P = 18 \n" ); document.write( "P = 2w -3 \n" ); document.write( "--------------- \n" ); document.write( "Solve for P and for w \n" ); document.write( "=========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
