3 times the first of three consecutive odd integers is 3 more than twice the third? what is the third integer

fenix001 [56]

Answer:

Step-by-step explanation:

The difference between consecutive integers is 1.

The difference between consecutive odd integers is 2.

Let the smallest odd integer be x.

Then the next greater one is x + 2. The greatest one is x + 4.

"3 times the first" is 3x

"twice the third" is 2(x + 4)

"3 times the first of three consecutive odd integers is 3 more than twice the third"

3x = 2(x + 4) + 3

3x = 2x + 8 + 3

x = 11

The smallest integer is 11.

x + 4 = 11 + 4 = 15

The greatest one is 15.

Can any one help me and work 2 or 3 of the problems for me to understand it

Alekssandra [29.7K]

To solve these problems you need to use the quadratic formula which is listed below.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

So, if you take #2.

The $x^{2}$ has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:

a = 1
b = -3
c = -3

Then you can plug all of these into the equation and simplify. Which gives you:

$\frac{3 -/+ \sqrt{21} }{2}$
