Answer:
7/10
Step-by-step explanation:
2/5 multiply the denominator by 2 which will make it 10. Then multiply the numerator by 2 which will make it 4. So it will be 4/10. Then add 4/10 to 3/0 which makes 7/10.

Answer:

2 possible solutions are c = 7, d = 3 and c = 8, d = 2
Step-by-step explanation:
Let d be the number of hours you walk dogs and c be the number of hours you wash cars. Note that 
1. You can work at most 11 hours next week, so

2. Your dog-walking job pays $9 per hour, so for d hours you will earn $9d. Your job as a car wash attendant pays $6 per hour, then for c hours you will be paid $6c. In total, you will earn $(9d+6c) that must be at least $60.
So,

3. You get following system of inequalities:

The diagram shows the solution set to the system of these inequalities.
2 possible solutions are c = 7, d = 3 and c = 8, d = 2
