Use the equation below to find a, if b= 4 and c= 15.
a=31-b-c
Idk

A=12

Step-by-step explanation:

A= 31 - B - C (Basic equation given to us)

then you sub in for the equation shown above

A= 31 - 4 - 15

then you can solve based on simple subtraction

A=12

a=12

Step-by-step explanation:

a=31-4-15

13-4=27

27-5=12

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
