Let us try to formulate the expressions one by one.
let the number be x.
Step 1:
six time the number is 6*x = 6x
Step 2:
product of the number and -3 is -3x
Step 3:
now let us make equation for it:
adding 3x on the left side,
dividing right side by 9
x=45/9 = 5
So the number is x=5
Original price of the laptop = P = $600
Rate of depreciation = r = 10% = 0.10
Time in years = t = 2
We have to find the worth of the laptop after 2 years. The given formula is:
Using the given values, we get:
Thus, the laptop will worth $486 in two years
Answer: C. 16.9
Step-by-step explanation: To find the perimeter you have to add all the sides of the figure.
Number 1 is x=2.2 and number 2 is x=4.3
