Please post others in separate post. As per the chegg guide line please post only 4 parts in a single post.

7.select part_number,part_description from part

8.select c.credit_limit from customer c
join orders ord on c.c_number=ord.c_number
join order_line ordl on ord.order_number=ordl.order_number
join part p on ordl.part_number=p.part_number and p.part_description='Gas Grill';

9.select w_no,sum(total_price) as total_value from
(
select a.warehouse_number w_no ,a.unit_price*b.number_ordered as total_price from part a
join order_line b on a.part_number=b.part_number
)
