Answer:

<h3>            Jake is 13 years old</h3>

Step-by-step explanation:

D      - age of Dani

J = D+2    - age of Jake

E = 2J = 2(D+2) = 2D+4    - age od Ethan

Z = 2E = 2(2D+4) = 4D+8    - age of Zoe

The sum of their ages is 102:

     D  +  J  +  E  +  Z  = 102

D + D+2 + 2D+4 + 4D+8 = 102

     8D + 14 = 102

         -14          -14

      8D  =  88

      ÷8        ÷8

      D = 11

J = 11+2 = 13

-5X^2 + 3X = -3X^2 + 3X - 50  solve for x ​
zhenek [66]

-5x^2+3x = -3x^2 +3x -50\\\\\implies 5x^2-3x^2 +3x-3x -50 =0\\\\\implies 2x^2 -50 =0\\\\\implies x^2 -25 = 0\\\\\implies x^2 = 25\\\\\implies x = \pm5\\\\\text{Hence}~ x = 5~ \text{or}~ x = -5
