Answer:
He will have $276.10 available towards the down payment for his motorcycle
Step-by-step explanation:
The compound interest formula is given by:
Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:
Compounded quarterly, so n = 12/4 = 3.
We have to find A.
He will have $276.10 available towards the down payment for his motorcycle
The answer is 5/7. That is the answer :)
This can be rewritten as
(x -6)² = 90 . . . . . the left side is already a perfect square
x -6 = ±√90 . . . . . take the square root
x = 6 ±3√10 . . . . add 6
Answer:
The answer to your question is x = -22; y = 4
Step-by-step explanation:
System of equations
2x + 5y = -24 ------------- l
3x - 5y = 14 ------------- ll
Process
1.- Multiply equation l equation l by 3 and equation ll by -2
6x + 15y = -72
-6x + 10y = -28 Add the equations
0 + 25y = 100
2.- Solve for y
y = 100/25
y = 4
3.- Substitute y in equation l to find x
2x + 5(4) = -24
Solve for x
2x + 20 = -24
2x = -24 - 20
2x = -44
x = -44/2
x = -22
