Let Tritt's age = t & Jan's age = 2t - 3
if the sum of their ages equals 30 then..
combine terms and simplify
now simply divide
and to find Jan's age just plug 9 in
Jan's age = 15
Tritt's age = 9
Answer:
<em><u>11 rides</u></em>
Step-by-step explanation:
<u>First Step - Subtract 6 from 40 because that will not be of use for now.</u>
<em>40-6=34</em>
<u>Next Step - divide 34 by 3 to find the number of rides.</u>
<em>(you will end up with a decimal so I rounded it up to a whole number.)</em>
<em>34/3=11 (rounded)</em>
<em><u>The final answer is 11 rides.</u></em>
<em>Hope this helped :)</em>

Answer:
(6x-5y)(20y-23x)
Step-by-step explanation:
x(6x - 5y) - 4(6x - 5y)^2
= (6x-5y)(x-4(6x-5y))
= (6x-5y)(x-24x+20y)
= (6x-5y)(20y-23x)
