Problem: One-half of Alvin's age two years from now plus one-third of his age three years ago

Mathematics
1 answer:
Nadya [2.5K]3 years ago

Answer:

24.

Step-by-step explanation:

Let's make the answer a variable, alright?

20 = (x - 3)/3 + 3(x + 2)

Get rid of the fractions.

120 = 2(x-3) + 3(x + 2)

120 = 2x - 6 + 3x + 6

120 = 5x

x = 24.

24 is your answer.

Convert 2671(in base 9), to base 3 without first converting to base 10.​
EleoNora [17]

Since 9 is 3², each digit in base nine takes two digits in base 3.

2₉ = 02₃

6₉ = 20₃

7₉ = 21₃

1₉ = 01₃

Putting it together

2671₉ = 2202101₃

Identify ALL the terms that are like terms with 3x^2.
shutvik [7]
I think it would be 4x^2 and 3x^3 because they both have the same "x". Because you can't add, for example, 5x + 7z, they aren't alike. That's why you have to choose like terms, for example, 5x+ 5x= 10x.

Fiona wants 6 red, 3 green and 3 yellow buttons on her dress. All buttons must be placed along a straight vertical line with no
elixir [45]

The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.

In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.

i.e _{n}P_{r} = \frac{n!}{(n - r)!}

Red      6

Green   3

Yellow  3

Total     12

Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.

Thus, n = 12 and r = 3;

_{12}P_{3} = \frac{12!}{(12 - 3)!}

      = \frac{12!}{9!}

      = \frac{12*11*10*9!}{9!}

      = 12 x 11 x 10

_{12}P_{3} = 1320

Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.
