Algebra.Com's Answer #400733 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! You are 8 now. In 4 years, you'll be 8+4 = 12. Since she will be half your age then, she will be 12/2 = 6 years old (4 yrs in the future). So she is currently 6-4 = 2 years old.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "She will be 20+2 = 22 years old in 20 years time. \n" ); document.write( " |
