He can make 27 different salads. Since each individual option has three different salads, and there are 9 options.
Basically multiply the number of total toppings by the number of toppings in each row
Answer: 27
All you have to do is 4 to the power of -3 and what that answer is you get y. You will do the same for 3. You will do 4 to the power of 3 which comes out to be 4*4*4.
When you multiply the first equation by 3, you get:
3 × 3x = 9x
3 × y = 3y (but when added, that part gets eliminated)
3 × 3 = 9
So you end up with
9x + 3y = 9
x - 3y = -2
(add)
10x = 7
So your answer is B. 10x = 7. I hope this helps!
