The variable is b, the coefinet is 1/3
remember
ab-ac=a(b-c)
1/3b-1/3=1/3(b-1)
there, factored
First you have to know how many inches are in a square cm and then the answer that you get for that first part you just multiply that by what you have but dont use a calcutor cause it wont give you the right answer because i had this before and i got it correct
1 is not. 2 is. 3 is not. 4 is. 5 is. 6 is. 7 is not. 8 is.
2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2
Answer: x = -2
Step-by-step explanation: vertical lines are the x axis
