Jim is growing a pumpkin for a competition at the county fair. In order for Jim's pumpkin to qualify, it must increase in weight 0.4 pound per week for seven weeks. If Jim reaches his goal to submit the pumpkin in the competition, after seven weeks the pumpkin will have increased in weight by pound(s).

 If he reaches his goal, the pumpkin will weigh 2.8 pounds more.

Step-by-step explanation:

To solve this question, we multiply 0.4 by 7 because if he needs the pumpkin to have gained 0.4 pound a week, for 7 weeks in total.

The answer is 2.8 pounds.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
