koby took$43 to movie theater. if he paid for 3 tickets that each cost d dollars, he will have 43-3d left. how much does he have left if the tickets cost $9.75 each?​

Koby has $13.75 left over after buying the tickets.

To find this answer, you use the equation given (43 - 3d) and fill in $9.75 for the variable "d". The equation now says "43 - 3 * $9.75", which you simply solve using PEMDAS.

3 * $9.75 = $29.25

$43 - $29.25 = $13.75

Thus meaning $13.75 is your answer. I hope this helps!

the correct answer is 45x

9×5=45 then add the x

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)
