So the other equation is
2.5 times as many kilos of rasins than sunflower seeds or
rasin kilos=2.5 times sunflower seed kilos
r=2.5s
the 2 equations are
12s+6r=108 and
r=2.5s
you can simplify the first equation (that sometimes helps)
undistribute the 6 from both left side
6(2s+r)=108
divide both sides by 6
2s+r=18
now use r=2.5s and subsitute 2.5s for r in first equation
2s+2.5s=18
4.5s=18
divide both sides by 4.5
s=4
subsitute
r=2.5 times s
s=4
r=2.5 times 4
r=10
rasins=10 kilos
sunflower seeds=4 kilos
The probability of any event is between 0 and 1. 0 means impossible and 1 means certain.
It could also be written with the percents: 0% and 100%.

Library: length 4, width 3 = 4(2)+3(2)=14
Take the length and width and multiply them by 5.
4*5=20 and 3*5=15
20(2)+15(2)= 70
The perimeter of the auditorium screen is 70.
I know that in some schools if your teachers feel you have what it takes to be in a higher grade level they might give you a choice to take a placement test to determine whether or not your ready to move up .
