To the left of z = -1.96 and to the right of z = 1.96 Using Standard Normal Deviation and the Z Table

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
