Let's raise the exponent three on both sides of the equation.
1/x^2 = (x^m)^3
1/x^2 = x^(3m)
1 = x^2.x^(3m)
1 = x^(2+3m)
X^(2+3m) = 1
For this to be true:
2+3m = 0
3m = -2
m = -2/3
Answer:
Step-by-step explanation:
To determine how much are you making on your investment, we will apply the simple interest formula. It is expressed as
I = PRT/100
Where
P = principal or amount invested,
R = interest rate
T = time
From the information given,
P = $1,500
T = 1 year
R = 8.5
I =( 1500×8.5×1)/100
I = $127.5
For a year you owe $1,600 on a credit card. You pay 19% interest a year on this credit card debt.
Interest paid = (1600×19×1)/100 = $304
The loss is 304 - 127.5 = - $176.5
Answer:
Step-by-step explanation:
s=3a
t=s+a
t=516
now lets use 3a instead of s.
516=3a+a
516=4a
a=129 (adult)
s=3(129)
s=387 (student)
The answer to number 2 is 7
