Hi! The answer for the first one is 500
50 times 9=450
10% is 50
50 times 10= 500
The original price was 500.
The discount was $50
For the second one the answer is $10
The discount was $7
10-7=3
10% is 1 , 30% is 3 and 70% is 7
When you write that equation, you get 3x^2+6=81.
Solving for x:
Subtract by 6 on both sides of the equation to get 3x^2=75.
Then, divide by 3 on both sides of the equation to get x^2=25.
Finally, do the square root on both sides of the equation to get x=5.
The number is 5.
Answer:
104F
Step-by-step explanation:
I'm not 100% sure if this is correct but here is how I did it:
