Answer:
x=9
Step-by-step explanation:
The expression is for the interior angle of the hexagon; one interior angle is equal to .
Since an interior angle of a hexagon measures 120°, we have the equality
.
Now it is just a matter of solving for
11x=120-21
11x=99
x=99/11
x=9
Rectangular book
two 8 1/2 sides
two 9 1/4 sides
8 1/2*2=17
9 1/4*2=18 1/2
17+18 1/2= 35 1/2
The perimeter of the textbook is 35 1/2 inches or 35.5 inches.
Hope this helps :)
Answer:
C. 18
Step-by-step explanation:
4-6 paris = about 23
10-12 pairs = about 5
28 - 5 = 18
(1) FOUR LESS THAN THE PRODUCT OF 4 AND A NUMBER is 4x - 5 = 5
(2) THE PRODUCT OF FOUR AND THE DIFFERENCE OF A NUMBER AND FIVE is 4 (x-5)
(3) THE PRODUCT OF FOUR AND THE SUM OF A NUMBER AND FIVE is
4 (x+5)
