Answer:
40% or 4/10 (assuming you just turned on the radio)
Step-by-step explanation:
If you just turned on the radio, it would be 4/10. If you changed from a channel that wasn't playing classical music then it would be 4/9. If you changed from a channel that was playing classical music then it would be 3/9.
So what you can do is:
3 breads * 4 meats * 7 toppings
Because there are four meats per each of the three breads and 7 toppings for each type of bread and meat combo.
so,
3 * 4 * 7
12 * 7
84
There are 84 sandwich combos.
- 9y - 4
factorise the numerator by taking out a common factor of 5y
45y² + 20y = 5y(9y + 4)
The expression now becomes
the 5y on numerator/ denominator cancel leaving
- (9y + 4) = - 9y - 4 ← quotient
