Answer:
3!2!/5! or 3/5 x 2/4 x 1/3 either way it makes 6/60 = 1/10
6x + 4y = 8
-4y = 12
6x + 4y = 8
y = 12/-4 = -3
6x + 4(-3) = 8
y = -3
6x -12 = 8
y = -3
x = (8+12)/6 = 10/3
y = -3 i guess
![4^{x} = 64](https://tex.z-dn.net/?f=%204%5E%7Bx%7D%20%3D%2064)
By taking <span>logarithmic of base 10
∴ </span><span>
![log 4^{x} = log 64](https://tex.z-dn.net/?f=%20log%204%5E%7Bx%7D%20%3D%20log%2064)
∴ x log 4 = log 64
∴
![x = \frac{log \ 64}{log \ 4}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7Blog%20%5C%2064%7D%7Blog%20%5C%204%7D%20)
∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
Well you equal out the two angles to each other and solve for x. then you just plug the the number you got for x back into the equations to get your answers
40(7.85) = 314
314 - (32.24 + 24.02 + 24.53) =
314 - 80.79 = 233.21 <== net pay
