Jane pulled weeds in the garden 7times. she was paid $5 each time she pulled weeds for less than 1 hour and $6 each time she pulled weeds for more than 1 hor. if jane received $39, how many times did she pull weeds for more than 1 hour?

Just assume that she did it less than 1 hour x times
and more than 1 hour y times
so you can get: 
and solve this equation system, you get:

If i drew it correctly, then al would also equal 14 in., because the midsegment divides the line ab into 2, equal in length lines.therefore, al = lb 

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60
