yes, why not?
oh thank you! The 8th grade class has 17 more girls than boys. There are 431 students in all. How many girls are there?
let x be the number of boys then x + 17 be the number of girls. x+x+17=431 2x=431-17 2x=414 x=207, this is the number of boys but, the question is the number of girls so, use x+17=207+17 is equal to 227. So, there are 227 girls and 207 boys in 8th grade class.
wow you are awesome! Can you help me with a few more?
Bob has one and a half times as much money as Ramon. Together they have $225. How much money does each have?
Let x be the money of Ramon and (1/2)x be the money of Bob. x+(1/2)x=$225 (3/2)x=$225 3x=2($225) 3x=$450 x=$150, this is the money of Ramon so, Bob's money will be (1/2 of 150) which is $75. Therefore, Bob has $75 while Ramon has $150.
thanks so much! one more?
