Answer:
x = 1 y= 3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
Simplify.
Add the two equations together to eliminate y from the system.
Divide each term by 8 and simplify.
Substitute the value found for x into one of the original equations, then solve for y.
The result can be shown in multiple forms.
Point Form:
(1,3)
Equation Form:
x=1 ,y=3

Answer:
$375.49
Step-by-step explanation:
- This question tests our knowledge of annuities
-Given the desired final amount is $25,000, the term is n=25 and the interest rate is 4%, the principal amount invested can be calculated as:

Hence, the annual deposits are $375.49
Im pretty sure she has 6 quarters and 12 nickels since it it twice as much.
$0.25 x 6 =150
$0.5 x 12 =60
total = 210
