Answer:
-1
Step-by-step explanation:
Took the assignment! :)
The answer is 70 . if it is 75 or higher then it wold be rounded to 80
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.
Answer:
The multiplicative identity property allows this to be true.
