1. Write the equation:
d(-3 + x) = kx + 9
2. "Open" the parenthesizes:
-3d + dx = kx + 9
3. Take kx to the left side, -3d to the right, everything with different sign (+ replace with - when transferring, - replace with +):
dx - kx = 9 + 3d
4. Factor x in the left side:
x(d - k) = 9 + 3d
5. Finally, divide the whole equation by (d - k):
x = (9 + 3d)/(d - k)
That's the final answer. Good luck!
I think it is fifty-four hundred
8 because when you flip one coin there is 2 outcomes: heads and tails. Therefore if you flip 3 of them it is 2*2*2=8
The cost of the car is $27,546
<h3>How to calculate the cost of the car ?</h3>
The sales tax is 7%
Jorge bought a ford mustang having a sales tax of $1,928.22
Therefore the cost of the car can be calculated as follows
7/100 = 0.07
1928.22/0/07
= 27,546
Hence the cost of the car is $27,546
