To get the total price multiply the cost of the book by 1 + sales tax rate:
7% as a decimal = 0.07
13.50 x 1.07 = $14.45
3 * C + 2 * M = 10.8
1 * C + 3 * M = 5.35
C = 3.1 $
M = 0.75 $ p
so B
The percentage change in house prices between 2017 and 2018 is -1.13%.
Percentage can be described as a fraction of a number expressed as a number out of hundred. The sign used to represent percentages is %.
In order to determine the percentage change in average house price, the difference between average housing pricing in 2018 and 2017 would be divided by the average house price in 2017 and the result would be multiplied by 100.

Answer:
x = 51 degrees
Step-by-step explanation:
Keep in mind, the angles of a triangle add up to 180 degrees.
A flat line also equals 180 degrees.
First, we should find the lower left angle. We know that 117 plus that angle is going to be 180, since it's a flat line.
180 - 117 = 63
Now, we just need to find angle x. (All 3 of our angles should add up to 180, knowing this, we can put it in an equation)
63 + 66 + x = 180
Then, you solve for x:
(63+66) + x = 180
129 + x = 180
-129 -129
x = 51
Hope this helps :)
