Answer:
-42/11
Step-by-step explanation:
x = y - 8
5x = 6 - 6y
So now solve the system of equations, divide everything in the second equation by 5 to get it to x = 6/5 - 6y/5
Now...
x = y - 8
x = 6/5 - 6y/5
Now substitute first equation into the second and x is gonna be -42/11 or the first number
The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)

Answer:
1486.67 or 1487.
Step-by-step explanation:
Find the average of those three things. Add 2,340 plus 470 plus 1650. You get 4460. Since you have three costs, divided 4460 by 3, which is 1486.6 repeating. Round to the nearest hundredth which is 1486.67. Hope this helps!
Answer:
y=2x+7
Step-by-step explanation:
2x−y+4=0
y=2x+4
m=2
Line are parallel, so their slope is the same.
A(-1,5)... x1 =-1,y1 =5
y-y1 =m(x-x1)
y1 - 5=2(x-(-1))
y1 - 5=2(x+1)
y1-5=2x+2
y=2x+2+5
y=2x+7
