Which of the following represents the inequality for the sum of 11 and y is greater than -33?
Arada [10]

Answer:

(c)  (11+y)   > -33  represents the inequality for the sum of 11 and y is greater than -33.

Step-by-step explanation:

According to the given question:

Sum of 11 and y is represented as (11 + y)

Now, the given sum is greater then -33.

⇒ Sum (11 +y)  is greater than - 33.

or, (11+y)   > -33

Hence, the expression (11+y)   > -33  represents the inequality for the sum of 11 and y is greater than -33.

Stella [2.4K]

Fifty-six biscuits are to be fed to 10 pets; each pet is either a cat or a dog. each dog is to get six biscuits, and each cat is to get five. how many dogs are there?

Answer: There are 6 dogs  

Explanation:

Total number of biscuits = 56

Total number of Pets = 10

Now each dog is to be given 6 biscuits and each cat is to be given 5 biscuits.

Now if there are 6 dogs and each is to be given 6 biscuits and total biscuits given to 6 dogs = 6 x 6 =36

and there are 4 cats and each is to be given 5 biscuits and total biscuits given to 4 dogs = 4 x 5 =20

Therefore, total biscuits given to 6 dogs and 4 cats is 36+20= 56
