Answer:
x+19=19+x
Step-by-step explanation:
If it uses 4 pieces of tape for a package...and each piece is 2.375 inches long, then it uses (4 * 2.375) = 9.5 inches per package.
and if u have 1900 inches of tape, 1900/9.5 = 200 packages can be sealed
Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.
We can make an equation that would help this. X will be the discount rate.
4x=3.60
Now, we need to solve the equation to find what X is.
Let's divide each side by 4.
x=.9
So, we know that the item was sold for 90% of what it was before, meaning that it has a 10% discount.
