Answer: 1/10
Step-by-step explanation:
From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.
To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:
= 7/10 - 3/5
Note that the lowest common multiple of 5 and 10 is 10.
= 7/10 - 6/10
= 1/10
Therefore, the answer is 1/10
3a+7+2a and 7a+5. These expressions are not equivalent. 5a+7 does not equal 7a+5.
Answer:

2n = -142
n = -71
