Answer:
(3, 3 )
Step-by-step explanation:
Given the 2 equations
3x - y = 6 → (1)
6x + y = 21 → (2)
Adding the 2 equations term by term will eliminate y, that is
(6x + 3x) + (y - y) = (21 + 6), that is
9x = 27 (divide both sides by 9 )
x = 3
Substitute x = 3 into either (1) or (2) and solve for y
Using (2), then
(6 × 3) + y = 21
18 + y = 21 ( subtract 18 from both sides )
y = 3
Solution is (3, 3 )
For a, x = 6 (3+6=9) and for b, y=5 (2x5=10)
Answer:105.00
A = $105.00
I = A - P = $5.00
Equation:
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 0.5%/100 = 0.005 per year.
Solving our equation:
A = 100(1 + (0.005 × 10)) = 105
A = $105.00
The total amount accrued, principal plus interest, from simple interest on a principal of $100.00 at a rate of 0.5% per year for 10 years is $105.00.
