Answer:
a = -2 or a = -5
Step-by-step explanation:
We want 
. We can subtract 2 from both sides of this equation to get 
. We can factor this to get that 
. When the product of two numbers is equal to zero, one of the numbers must be equal to zero. This means that either a + 2 = 0, in which case a = -2, or a + 5 = 0, in which case a = -5.
12 toys. Dividing 15 by 60 equals 4 so 4 tots in a hour. Then multiple the 4 toys an hour by 3 hours.
Step-by-step explanation:
First;
