Maggie‘s brother is 11 years younger than four times her age. The sum of their ages is 54. How old is Maggie?
lbvjy [14]

Answer:

Maggie is 13

Step-by-step explanation:

Honestly, I just kept trying ages starting from 10 because I knew it wasn't going to be less than that. Then I did whatever age, in this case 13, and multiply it by  4. Then minus 11 from that number. Then take that end number and add it to the beginning number(maggies age) and you should get 54.

Math Equation Explanation:

13*4 = 52                           (Maggies Age) x 4

52-11= 41                            The question stated that Maggie's brother was 11                                             -------------------------------------years younger than her age times 4.

41 + 13 =54                          The sum of both their ages.

X2 − 6x + 8 > 0 solve
Masja [62]

Hello :

x²- 6x + 8 = x² - 2(3)(x) +8

                = (x² -2(3)(x) +9) - 9 + 8

               = ( x - 3 )² - 1²

               = (x - 3 + 1 ) (x - 3 - 1 )

x²- 6x + 8 = (x - 2 ) ( x - 4 )

x      - ∞             2             4              + ∞

ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ

x - 2       --------    0   +++++   +++++++

x - 4      ---------          --------  0  +++++

(x - 2 ) ( x - 4 )  +++ 0 ------ 0 ++++++  

x2 − 6x + 8 > 0   the solution in :  ]-∞:2[ U   ]4;+∞[
