Answer:

Step-by-step explanation:
This problem lays out pretty clearly what needs to be done.
First, we know that we are writing an inequality.
Then, it tells us that we need 'the product of x and 7'. A product is the result of multiplication, so we can multiply 7 and x together to get 7x.
Next, it tells us that the product (7x) is at least 15. At least means that the product has to greater than or equal to 15. That clue tells us which inequality symbol will be used.
Put it all together and:

Answer:
60 lb
Step-by-step explanation:
Represent the weights of the dogs by P and C. Then P = 3C.
Then P + C = 80, or, after substitution of 3C for P,
3C + C = 80, or
4C = 20, so that C = (20 pounds)
Paula's dog weighs 3 times as much as Carla's: P = 3(20 lb) = 60 lb
