HELP Last year, "Raina" opened an investment account with $6500 . At the end of the year, the amount in the account has increased by 23% .

year end amount=_ X original amount

Year end amount_

principal=$6500

time=1year

rate=23%

Step-by-step explanation:

amount=p(1+r/100)^t=$6500(1+23/100)=$6500×1.23=$7995 is total end amount.

interest gain=total end amount- principal=$7995-$6500=$1495

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
