The 500 in the equation represents the initial amount deposited in the bank before the weeks start counting.
<h3>Linear equation</h3>
Linear equation is an equation in which the highest power of the variable is one.
Therefore, the modelled equation represents a linear equation.
where
w = number of weeks since the account was opened
The equation models the balance in her account. This equation tells us each week the owner deposits 25 units amount.
Therefore, the 500 in the equation represents the initial amount deposited in the bank before the number of weeks start counting

Answer:
ST = 4
Step-by-step explanation:
RS + ST = RT, substitute values
3x - 8 + x = 2x, that is
4x - 8 = 2x ( subtract 2x from both sides )
2x - 8 = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus ST = x = 4
