Answer:
-6 = x
Step-by-step explanation:
3 sqrt (5x-4) = 3 sqrt (7x+8)
Divide each side by 3
3/3 sqrt (5x-4) = 3/3 sqrt (7x+8)
sqrt (5x-4) = sqrt (7x+8)
Square each side
(sqrt (5x-4))^2 = ( sqrt (7x+8) )^2
5x-4 = 7x+8
Subtract 5x from each side
5x-5x-4 = 7x-5x+8
-4 = 2x+8
Subtract 8 from each side
-4-8 = 2x+8-8
-12 = 2x
Divide by 2
-12/2 = 2x/2
-6 = x
1 km = 1,000 m
1 m = 1,000 mm
therefore
1 km = 1,000 m = 1,000 · 1,000 mm = 1,000,000 mm
2 km = 2,000,000 mm > 3,000 mm
Answer: 3,000 mm is less than 2 km.
