Answer:

nth term = 7n - 2

Step-by-step explanation:

a = first term = 5

d = common difference = second term - first term

  = 12 - 5 =7

d = 7

a_{n} = a + (n-1)d

    = 5 + (n -1)7

    = 5 + 7n - 7          {add like terms}

    = 7n - 2

Claude purchased a container of peanuts that weighs 4 kilograms. Taryn purchased a container of peanuts that weighs 4,100 grams.
Vilka [71]

Answer: 100 grams

Step-by-step explanation:

From the question, Claude purchased a container of peanuts that weighs 4 kilograms. We can convert this to grams and it'll be:

= 4 × 1000 grams = 4000 grams.

Taryn purchased a container of peanuts that weighs 4,100 grams. The difference will then be:

= 4100 grams - 4000 grams

= 100 grams

Taryn bought 100 grams more.

gladu [14]

Answer:

Please check the explanation.

Step-by-step explanation:

  • Given that Chris spends 35% of his budget on rent for his apartment.

We need to write 35% as a fraction, percent, and a decimal.

35% as a fraction:

All we need is to divide 35 by 100 as 35 is basically the 35th part of 100 parts.

Thus, 35% as a fraction would be: 35/100

35% as a decimal:

All we need is to divide 35 by 100 and calculate the result such as:

35/100 = 0.35

Thus, 35% as a decimal would be:  0.35

35% as a percent:

35% is already mentioned as a percent.  

Thus, 35% as a percent would be:  35%
