Hey there!
36y - 12
FIRST LOOK AT THE GCF (Greatest Common Factor)
36y: 1, 2, 3, 4, 6, 9, 12, 18, 36, and y
12: 1, 2, 3, 4, 6, and 12
GCF: 12
So, 12 would most likely be number before you make your parentheses
12(?y - 1)
The numbers in your original equation both share 3 & -1
So, therefore the factor form of your equation should be: 12(3y - 1)
Answer: 12(3y - 1)
Good luck on your assignment & enjoy your day!

Sounds like rearranging to me:
P=2(a+b) -- expand brackets
P=2a+2b -- subtract 2a
P-2a=2b -- divide by 2
b=(P-2a)/2
To find an average you take the numbers to be averaged and add them together then You take the number and divide it by the number of numbers, in this case 4, and that gives you the average.
on this problem you want to do the opposite. you know the average she wants, an 87, so you multiply it by 4. 87*4=348. then you add the three numbers you have (88,81 and 87) and you get 256.
then you subtract 256 from 348 and you get 92. 92 is your answer to check just add 87+81+88+92=348
348/4=87
87 was the average she wanted.
Hope this helped! good luck :)
0.625
divide 5 by 8 is 0.625 rounded would be 0.63
