Answer:

c=12

Step-by-step explanation:

P=a+b+c

28=5+11+c ; combine 5 and 11.

Answer:

c = 12.

Step-by-step explanation:

Fill in what you know. 28 = 5 + 11 + c. Add 5 and 11 together. 28 = 16 + c. Then subtract 16 from both sides 28 - 16 = 16 - 16 +c. Then the number you have left is your answer.

Mkey [24]

Answer:

5x² - 13x - 6

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

5x(x - 3) + 2(x - 3) ← distribute both parenthesis

Inessa05 [86]

Answer:

Option C is the correct answer.

Step-by-step explanation:

For a fair decision to be made during the process, the number of persons in the set must be a divisor of 28.

Let's list the divisors of 28:

The divisors of 28 are {1, 2, 4, 7, 14, 28}

The only option that contains one of the divisors is option C which is 7.

Helen [10]

Answer:

6 cases

Step-by-step explanation:

Kendra wants a total of 160 water bottles

She already has 16 water bottles. So you can subtract 16 from 160 or

160-16 = 144

Then since there are 24 water bottles in a case, you need to divide 144 by 24 or 144÷24 = 6
