Answer:
x= 1
Step-by-step explanation:
7x-4x= -1+4
3x = 3
x= 1
Answer: x = 20
Step-by-step explanation:
Right angle = 90
90 - 47 = 43
43 - 3 = 40
40/2 = 20
Original price of the item = $14.95
Price after discount = $13.79
Discount offered = original price - price after discount = 14.95- 13.79 = $1.16
Now let us find the percentage of discount offered.
Percentage discount is given by the formula:

Where MP= Marked price= original price
SP= selling price= price after discount

Percentage discount = 7.759 %
They are not, because inverse means multiply by -1, therefore, there should be a positive sign in front of 2 and a negative in front of x for G(x) = x - 2
