The ratio is 3:2, purple :green
The bag has 21 purple so to get from 3 to 21 it is multiplied by 7; so we must also multiply the 2 by 7 to keep the ratio balanced.

Answer:
you can either factorise or use tge formula method
Answer: The equation has one solution
Step-by-step explanation: First , open the brackets
7( 12 - 2x ) = 4 (3 - 3x )
84 - 14x = 12 - 12x
collect the like terms
84 - 12 = - 12x + 14x
72 = 2x
Therefore divide through by 2
x = 72/2
x = 36
Therefore, the equation has only one solution
4(6)-6(3)+(8)
24-18+8
6+8
14
The answer of 12 to 13 is almost correct - you only forgot the - signs
As for the decimal estimate, take the square root of 12 (144) and the square root of 13(169) and because 150 is closer to 144 than 169 we can guess that the decimal is about -12.2
