Answer 1

A = 1000  if   0.645 x 10 = 6450 / A

Step-by-step explanation:

0.645 x 10 = 6450 / A

=> 6.45  = 6450 / A

multiplying both sides by A

=> 6.45 A  = 6450

=> 645 A /100  = 6450

multiplying both sides by 100

=> 645A  = 645000

Dividing both sides by 645

=> A = 1000

A = 1000  if   0.645 x 10 = 6450 / A
