Since the total of exterior angles of a plane figure is always 360, you would divide 360 by 20 which gives you 18
Answer:
9r
Step-by-step explanation:
1.5r - 3r + 10.5r
10.5r + 1.5r = 12r
12r - 3r = 9r
Final Answer = 9r
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
Answer:
The perimeter of the larger hexagon is 54 yards
Step-by-step explanation:
The ratio is 5/9
So the ratio of the perimeters is going to be the same
5 30
--------- = ----------
9 P2
5 * P2 = 30 * 9
5 * P2 = 270
Divide each side by 5
5 P2 = 270/5
P2 =54
The perimeter of the larger hexagon is 54 yards
99.8 off because if you subtract it and it will be 99.8 off
