evaluate the following expression if x = –4.28, and y = –4.68. Round your answer to the nearest tenth.x – 5y

math 
DrBob222,
x5y
4.28 5(4.68) =
4.28 + 23.40 = +19.12
Now you round to the nearest tenth. 
math 
Damon,
well 5 y = 23.4
so
x  5 y = 4.28  (23.4)
minus a minus is a plus
so
x  5 y = 4.28 + 23.4
= 19.12 which to the nearest tenth is 19.1 
whoops typo 
Damon,
well 5 y = 23.4 forgot minus sign
so
x  5 y = 4.28  (23.4)
minus a minus is a plus
so
x  5 y = 4.28 + 23.4
= 19.12 which to the nearest tenth is 19.1
