That would be 8. first parenthesis, then multiply, then subtract.
7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)

This is not possible, as -6 is not equal to -4.
87.5 you see you need to multiply .25 by 35.If there are zeros at the end of a decimel
you can remove them good luck
Answer:
1007
Step-by-step explanation:
The volume of the cylindrical storage tank is : π·40(squared)·60 = approximately 302000.
The volume of a rectangular prism is : 5 x 6 x 10 = 300
To catch all the leaking liquids, you need : 302000 : 300 = 1006.6666667 (round to 1007) rectangular prisms
