69. The jacket is said to have an original price of 45.00 dollars.
Now, is was given a 25% off.
Solve for the final cost of the jacket after the discount is applied.
=> 25% = 25% / 100% = 0.25
=> 45.00 * .25 = 11.25 dollars is the discount.
Now, let’s subtract the value of 25% by the original value.
=> 45 – 11.25 = 33.75 dollars.
This is now the costs of the jacket after the discount is applied.
Answer:
slope : 1/15
Step-by-step explanation:
slope = change in y / change in x
change in y = 1 / change in x = 15
therefore, 1/15 = slope
Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16
