Hello! Let's work this problem from left to right to make things a bit easier ;)
6.5+(-2) is the same as 6.5-2, since adding a negative is the same as subtracting a positive. 6.5-2=4.5
Now, we have to add 10.5 to 4.5, which gives us the grand total of 15. I hope this helped! Let me know if you need anything else!

Answer:
Math expression= L[m]= W[g] / R[g/m]
answer=4.606Km
Step-by-step explanation:
It is known that the cable weighs 44kg / km therefore if the weight is divided by this amount we can find how much cable length was spent
L=W/R
L= leght of wire used(m)
W=weight used(g)=205g
R= relation between weight and leght(g/m)=44.5g/km=0.0445g/m
L=205g/0.0445g/m= 4606.74m= 4.606Km
