**french exam tomorrow, WHAT DO I DO?!**

Just study i know you should get some sleep but if you dont study you will fail just study study study

-6/7,-1/2,1/7,2/7,3/7

**math**

Two odds =even, ex: 1+1=2, 5+9=14, 77+3=80 ... you always get an even when adding two adds 1odd+1even =odd ex: 2+5=7, 11+8=19, 101+2=103 ... you always get an odd,

**math**

1 is an odd number, but 1 doesnt count for prime number, if this is the rule you were thinking about

**math**

let spped of current be X, when the boat goes upstream, the actual speed of boat= speed of boat-speed of current;when the boat goes downstream, the speed =speed of boat+speed of current distance=speed x time upstream: (16-X)x 1/3 downstream:(16+X)x1/4 since the total distance ...

**geometry**

1,2,6,24,120,..[720,5040] 2/1=2, 6/2=3,24/6=4,120/24=5, what you need to find out is a number that can be divided by 24 and gives you 6, 2,4,8,16,32,.. [64,128] each number times 2 gives you next number 1,1/4,1/9,1/16,1/25,.. [1/36,1/49] the denominators are 2 square, 3 square...
