Answer:
Cody has solved (12 × 12) = 144 problems.
Step-by-step explanation:
For every one problem that Julia completes, Cody completes twelve.
If Julia Completes x problems and Cody completes y problems, then we can write y = 12x ........ (1)
Now, given that the number of problems solved by Cody is one hundred twenty more than two times the number of problems solved by Julia.
Hence, 2x + 120 = y ......... (2)
Now, from equations (1) and (2) we get,
2x + 120 = 12x
⇒ 10x = 120
⇒ x = 12
Therefore, Cody has solved (12 × 12) = 144 problems. (Answer)

Answer:
Step-by-step explanation:
It is necessary to add the whole numbers of fractions from left to right in order to solve this problem.
<h3>3 3/5+1 1/6</h3>
<u>First, you have to add the whole numbers.</u>
3+1=4
<u>After that, you can combine by a fraction.</u>
6*3=18
18/5+ 1 1/6
1+6=7
7/6
<u>Rewrite the problem down.</u>
18/5+7/6
<u>Solve.</u>
5*6=30
143/30
=23/30
- <u>Therefore, the final answer is 4 23/30.</u>
