This problem was from my SAT test on May 7th...which I thought the problem was REALLY easy..(well it looked easy), but I couldn't get it.
The problem n is a two digit number. If n is divided by 10, the remainder is 9. Also, if n is divided by 7, the remainder is 8. What is n? All the math brainiacs....answer that one please. |

When you can't figure it out algebraically..just plug in random numbers until you get the desired product..
You knew it was a two digit number and that you would get a remainder of 9 if you decided it by 10. Therefore..it has to be 9 more than a two digit number that ends with 0..so go through the list. 19, 29, 39, 49, 59, 69, 29, 89..like that. Just a tip. o_O. |
