There are 6 pencils left over.
1,000 divided by 7 = about 142
So each teacher got 142 pencils
142 x 7 = 994
1,000 - 994 = 6
Answer:
There is no solution because the slopes of the line are the same.
Step-by-step explanation:
4y - 4x = 48
+ 4x + 4x Add 4x to both sides
4y = 4x + 48 Divide both sides by 4
y = x + 12
Now set both equations equal to each other since they equal y
x + 12 = x - 11
-x - x Subtract x from both sides
12 ≠ -11 No Solution
