Answer:
1430 m
Step-by-step explanation:
1 km = 1000 m
3000 cm = 30 m
1000 + 400 + 30 = 1430
The multiplicative inverse of a number x is a number y such that their product xy is 1.
So, we want a number such that

Divide both sides by 10:

X = 66 degrees. (Co interior angles are supplementary, add up to 180)
2y + 4 = y + 7
2y - y = 7 - 4
Y = 3
