find three consecutive odd integers such that the sum of the smallest number and middle number is 27 less than 3 times the large
katrin2010 [14]

A generic odd number can be written as

2k+1,\quad k \in \mathbb{Z}

Since there is an odd number every two numbers, three consecutive odd numbers will be

2k+1,\quad 2k+3,\quad 2k+5

Now let's make up the equations: the sum of the first two is

(2k+1)+(2k+3)

And 27 less than 3 times the largest is

3(2k+5)-27

These two must be the same, so we have

(2k+1)+(2k+3)=3(2k+5)-27 \iff 4k+4 = 6k+30-27 \iff 4k+4=6k+3

Subtracting 4k and 3 from both sides gives

1=2k \iff k=\dfrac{1}{2}

Which means that the problem has no solution.

To confirm this hypothesis, we can observe that, on the left hand side, we have the sum of two odd numbers, which is even

On the right hand side, we have an odd number, multiplied by 3 (still odd), take away 27 (still odd).

So, the left hand side is even, and the right hand side is odd. They can't be the same number.

Please help me thank you!!!

Answer:

25

Step-by-step explanation:

Alll angles of a triangle = 180 degrees

36+61 = 97

180-97 = 83

It means that the other angle will be of 83 degrees.

means

4x-17 = 83

So now, we can do transposition.

Let's transpose 17.

4x-17 = 83

Transpose 17

4x = 83+17

4x = 100

Now we will transpose 4.

x = 100÷4

x = 25

Hope it helped!!!

Step-by-step explanation:

but for c if its 1 bag per teacher (like i think it is) then i multiplied 2299850.19 by 70 and i got = 160989513.3
