Here, we are to solve for the value of x in the given euation;
2/(3x-9) = 6
We can solve this by making a cross multiplication
2/(3x-9) = 6/1
The cross-multiplication would yield;
2 * 1 = 6 * (3x-9)
2 = 6(3x-9)
opening the bracket, we have
2 = 18x - 54
Collect like terms;
54 + 2 = 18x
18x = 56
divide both sides by 18
18x/18 = 56/18
x = 28/9
x = 3 1/9
Answer:

Step-by-step explanation:
From the question we are told that
Charge 
Force 
Generally the equation for electric field strength is mathematically given as


Therefore

Maggie = x years old
Demarco = x + 4
Anna = 3*Demarco
Anna = 3*(x + 4)
Anna = 3x + 12
Hope this helps!
Answer: 5/6
Step-by-step explanation:
Over 2 there are 4 numbers 3,4,5,6 but it can be odd so also 1 works there are 6 numbers in total and 5 numbers work so
5/6
