Kindly refer to attachment for solution.
Hope it helps ^_^
This is just like an exponential growth equation...
Final=initial*rate^periods
25000=12500(1.0525)^t
2=1.0525^t
ln2=t ln1.0525
t=ln2/ln1.0525
t=13.55
t=14 yrs
Expression: 5x + 12
Coefficients (The number directly next to the variable): 5
Variable (A letter that stands for a unknown number): x
Term (A single mathematical expression): 5x , 12
Constant (A term that has no attached variables): 12
Answer:
x=3 y = 4
Step-by-step explanation:
3x+5y=29 .........*2 (multiply by2) = 6x+10y=58
2x+3y=18 *-3 = (multiply by -3)= -6x-9y = -54
ADD both(-6x cancels 6x) y= 4
2x+ 3y = 18 2x+ 12 = 18 2x = 6 x = 3
