HACTEHA [7]

Answer:

4 books

Step-by-step explanation:

We are told that: Hugh bought some magazines that cost 3.95 each

Hugh bought 3 magazines.

Hence, total cost of magazines = 3 magazines × 3.95

= 11.85.

Total cost of magazines = 11.85

From the question, we know that, the total amount Hugh spent = 47.65

Hence, The total cost for books =

Total amount spent - Total cost of magazines

= 47.65 - 11.85

= 35.80

Therefore, the total cost of books = 35.80

We are told in the question that the cost of books is 8.95 each or 8.95 per book.

Hence, the number of books that Hugh bought is calculated as :

35.80/8.95

= 4 books

Therefore, Hugh bought 4 books

c^2(c+4) - 3c(c+4) + 5(c+4)

c^3 + 4c^2 - 3c^2 - 12c + 5c + 20

Paula has a dog that weighs 3 times as much as Carla's dog. The total weight of the dogs is 80 pounds. How much does Paula's dog
Vedmedyk [2.9K]

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
