3/4 = 30/40 so therefor b 33/40 is greater than 30/40 is correct
Answer:
2 sessions, $231
Step-by-step explanation:
Make an equation (let x represent the number of sessions)
59+86x=63+84x
Subtract 84x from both sides
59+2x=63
Subtract 59 from both sides
2x=4
Divide by 2
x=2
At 2 sessions they will be equal
To find the cost, substitute 2 in for x
59+86(2)=63+84(2)
59+172=63+168
231=231
So, at 2 sessions the plans will cost the same at $231
Hope this helps! :)

Answer:
son age: X
man_age= 5X
in 3 years: we have: (man_age+3)(X+3)=380
we can replace the man age by 5X and we get :
(5X+3)(X+3)=380
it is a quadratic equation with 2 solutions. One negative and 7
The solution is thus 7, since age can not be negative.
The son is thus 7 and the dad 5 times more 35
