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

Can you help me with this problem: Elena and Jada both read at a constant rate, but Elena reads more slowly. For every 4 pages t
Paraphin [41]

4 pages Elena = 5 pages Jada

To figure out how many pages Jada reads if Elena reads 1, divide 5 by 4: 1.25. This means that for every 1 page Elena reads, Jada reads 1.25 pages.

So if Elena reads 9 pages, multiply 1.25 by 9: 11.25 pages that Jada reads.

For S pages read by Elena, this is a variable, so I’m assuming it means for every S pages, Jada reads 1.25S
