Answer:
$2000
Step-by-step explanation:
The amount of interest you pay (for simple interest) is the product of the original amount, the interest rate and the time in years. Let x be the original amount (how much money she borrowed):
720=x(0.09)(4)

Answer:
1 / q^3 = 1 / q^n
n = - 3
Step-by-step explanation:
1/r^-4 = r^4
p^3 * q^2 * p^4 * q^n * r^3 * r^4 = p^7 q ^5 r^7
(p^3 * p^4 *q^2 * r^3 * r^4 ) / ( p^7 * q^5 * r^7) = 1/q^n
(p^7 * q^2 * r^7) / (p^7 * q^5 * r^7) = 1/q^n
q^2 / q^5 = 1/q^n
1 / q^3 = 1 / q^n
Answer: 3
Step-by-step explanation:
Let x = the number
x + 3 = 4x - 6
-3x = -9
x = 3
