Answer:

A= 429

B= 50

Explanation:

A+B= 479 (take away)

A-B= 379

A-A+B+B= 479-379 (simplify)

2B= 100

I think you know how to do it now..

B=50

A=50+379 ---> 429

This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!

10,000/10=1,000

Step 2: Divide 10 by 1,000 (to find our answer)

10/1,000=0.01

Our answer is 0.01. The volume of 10 drops of liquid is 0.01 fluid ounces.
