Answer:
20 green pencils
Step-by-step explanation:
The difference between black and green "ratio units" is 7 -5 = 2. The difference between red and blue ratio units is 3 -2 = 1. The sum of those differences is 2 +1 = 3 ratio units, which represent 12 pencils. Then each ratio unit represents 12/3 = 4 pencils.
The 5 ratio units of green pencils represent 5·4 pencils = 20 green pencils.
_____
If you need an equation, you can use k as the constant of proportionality. Then the sum of differences described is ...
(7k -5k) + (3k -2k) = 12
3k = 12 . . . . simplify
k = 4 . . . . . . divide by 3
5k = 5·4 = 20 . . . . . number of green pencils
Answer: green angle = 76 degree
Solution:
We can use interior angle properly of a triangle to find it.
Exterior angle = sum of interior angles
So, 116 = 4x + (7x + 6)
11x + 6 = 116
11x = 116 - 6
11x = 110
x = 110/11 = 10
So, angles = 4 x 10 = 40
7 x 10 + 6 = 70 + 6 = 76
Green angle: 76 degree
