Answer:
The rules for adding and subtracting signed decimals are almost the same as the rules for adding and subtracting integers. When dealing with decimals, you need to be especially aware that your decimal points are lined up so that you do not accidentally add or subtract in the wrong place.
189 is 45% of 420 and 198 is 55% of 360
189 = .45x
/.45 /.45
420 = x
198 = .55x
/.55 /.55
360 = x
Put the numbers given accordingly in the equation
bracket means multiply
2(-2)-5(5)-3(-2)
=-4-25+6
=-23
a. -23
