Question

What is the value of the expression? 19.2+(–7+3.8)

a. 16
b. 24
c. 29
d. 30

Answer 1

The first thing I would do to solve this is do the () so -7+3.8=-3.2 +19.2=16 So your answer would be A. I hope this helps. :)

Answer 2

`19.2+(-7+3.8)=19.2+(3.8-7)=19.2+(-3.2)\\\\=19.2-3.2=\huge\boxed{16}\leftarrow\boxed{a}`
