Answer:
40.802 
Step-by-step explanation:
4x10+(8x1/10)+(2x1/1000)  is found by calculating the three different terms (with different powers of 10) separately and then adding these results together:
4*10 = 40
8*(1/10) = 0.8
2*(1/1000) =.002
Summing up these results, we get:
40.802

w-(-3)=7
Pretend that there is a -1 in front of the bracket
w-1(-3)=7
Mutiply the bracket by -1
(-1)(-3)=3
w+3=7
Move +3 to the other side. Sign changes from +3 to -3.
w+3-3=7-3
w=4
Answer: w=4
