8 stamps. Multiply 2/3 by 12 and you have your answer
Answer:
If P= price of the hardcover book, then
We have to spend $25-P, if P<$25; or $0 if P>= $25
Step-by-step explanation:
Lets call P the price of the hardcover book, in $. We can suppose that P is less than 25, otherwise we shoudnt spend on anything else to get the free shipping. If X is the amount that we have to spend to reach 25, then we get that P+X = 25. If P is known, we can obtain X by substracting P in both sides, therefore
X = 25-P
We conclude that if the price of the book P is less than 25, then we have to spend $25-P. Otherwise we have to spend 0.
Step -by-step explanation: the opposite of a number is the number on the other side of the numbers line eg -5 is the opposite of 5 so-12% is the opposite of 12%
Answer:-12%
Answer:
c) 72
Step-by-step explanation:
multiply 18 by 4
Answer:
x ≈ 20.42, y ≈ 11.71
Step-by-step explanation:
Using the cosine ratio on the right triangle on the right, that is
cos20° = 
= 
Multiply both sides by y
y × cos20° = 11 ( divide both sides by cos20° )
y = 
≈ 11.71
Using the sine ratio on the right triangle on the left, that is
sin35° = 
= 
= 
Multiply both sides by x
x × sin35° = 11.71 ( divide both sides by sin35° )
x = 
≈ 20.42
