A= 5 + 2 = 7 You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this X+2= 7 -2. -2 ——— X= 5
B: 15-4=11 +4. +4 ————- X= 15
C: 4(3) = 12
D: 50/5 = 10
Btw this should be easy, try doing it on to your own now.
<u>the density of electrolyte solution is 100 ampere per square meter</u>
<h2>Step-by-step explanation:</h2>
We know that the Average current density of the solution = 1 ampere per square decimeter and we need to find the average current density of the solution in ampere per square meter. So
