12a. First expressing as a fraction, Shan has 12/32 books from his favorite author, so:
12/32=3/8=0.375 books from his favorite author
12b. Because the decimal 0.375 isn't a periodical decimal, so it would be a terminating decimal.
So for this problem, let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount.
Answer: -2 and -7 i think
Let x = your number.
(x - 17) * -7 = -35. Divide each side by -7.
(x - 17) = 5. Add 17 to each side.
x = 22.
Your number is 22
Answer:
18.7939 m
Step-by-step explanation:
-Let x be the distance between John and clock tower.
-Let y be the vertical distance from the eyes of the two men standing to the top of the clock tower.
#Taking the right triangle ACD:

#Taking the right triangle ABD:

#We equate the two yo solve for x and y;

Hence, John's distance from the tower's base is 18.7939 m
