Answer:
The correct answer is 85.7
Step-by-step explanation:
1st you take 428.5 and divide by 5 and boom
This much, I understand from that
1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...
ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...
y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==
y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==
Answer:
x=0
y=1.5
Step-by-step explanation:
I think you need to figure it out to 3. if you dont it wont make sense until you figure it out. maybe do what you know. you are given the first two answers. then you figure out how to prove it.
