Answer :
There are two cases in this problem :
1). When the ion is positively charged :
Now, the ion and the substance both are positively charged hence when brought together will repel each other because equal charged particles repel each other.
2). When the ion is negatively charged
Now, the substance is positively charged and the ion is negatively charged so both will attract each other because the particles with opposite charges attract each other.
The base is 6.
In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.
x + 1 = -x + 7
2x + 1 = 7
2x = 6
x = 3
Now that we have the value for x, we can plug into the equation to get the value for the base.
3x - 3 = base
3(3) - 3 = base
9 - 3 = base
6 = base
Answer: £ 400,560,640
Step-by-step explanation:
Given
Delia, Edwin, and Freya share £1600 in the ratio
