Answer:
P = $41,820.01
Step-by-step explanation:
A = P(1 + r/n)^nt
P = A / (1 + r/n)^nt
Where,
P = principal
A = future value = $50,000
n = number of periods = 4
r = interest rate = 6% = 0.06
t = time = 3 years
P = A / (1 + r/n)^nt
= 50,000 / (1 + 0.06/4)^4*3
= 50,000 / (1 + 0.015)^12
= 50,000 / (1.015)^12
= 50,000 / 1.1956
= 41,820.01
P = $41,820.01
Answer:
7+12x+2y
Step-by-step explanation:
3-8+(12x + 12)+2y=
-5+(12x +12)+2y=
7+12x+2y
Its s hope it helps i looked at it in google as well.
Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
