we know that
1) Mailyn can eat 32 cookies in an hour
1 hour is equal to 60 minutes
<u>Find how cookies eats Mailyn in one minute</u>
by proportion

2) Juan needs 3 hours to eat 32 cookies
<u>Find how cookies eats Juan in one minute</u>
by proportion

<u>3) Find how long will it take them to eat 40 cookies together</u>
we know that
Maylin and Juan eats in one minute together ---------> (0.53+0.18)=0.71 cookies
so
by proportion

therefore
<u>the answer is</u>

Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
3x/4+3=20
<=> 0.75x +3 =20
<=> 0.75x = 17
<=> x = 68/3
The equation would be L = 1d + 45
After 21 days it would be
L = 1(21) +45
L = 21 + 45
L = 66 miles after 21 days
