Answer:
n = 28 degree
Step-by-step explanation:
2n + 17 + 2n - 5 + 2n = 180 degree (sum of interior angles of a triangle)
6n +12 = 180
6n = 180 - 12
n = 168/6
n = 28 degree
Answer:
There are 30 books in the shelf.
Step-by-step explanation:
To solve this problem we can use a rule of three in such a way that 12 paperback mysteries are related to 40% of the books in the shelf in the same proportion that "x" total books are related to 100% of the books in the shelf. So we have:
12 -> 40%
x -> 100%
40*x = 12*100
40*x = 1200
x = 1200/40
x = 30 books
There are 30 books in the shelf.
Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0
