Answer:
-2
Step-by-step explanation:
-6x=5x+22
-6x-5x=22
-11x=22
x=22/-11
x=-2
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
In the problem -5+x=0, x=5
Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.
Answer:
62°
Step-by-step explanation:
The diagonals of a rhombus are perpendicular bisectors of each other, and each bisects the angle at a vertex of the rhombus. So, ∠DCG is the complement of ∠CDG, which is congruent to ∠EDG. We believe the marking 28° is intended to apply to ∠EDG, which would mean that ...
m∠DCG = 90° - 28°
m∠DCG = 62°
