Answer: i dont know if it is only me but i cant see the photo.
Step-by-step explanation:
190x + 210x = 2000
400x = 2000 <-- Combine like terms
x = 5
In 5 hours they will separated by 2000 miles.
Answer:
420 cm, 4.3 meters, 4600 mm, 0.04 km
Step-by-step explanation:
We can solve this by converting each to the same unit. I will be using meters.
0.04 km
1 km = 1000 meters
1000 meters / 1 km = 1
multiply 0.04 km by 1 = 1000 meters / 1 km , keeping the km at the bottom to cross out
0.04 km * 1000 meters / 1 km = 40 meters
420 cm
100 cm = 1 meter
1 meter / 100 cm = 1
multiply 420 cm by this, keeping cm at the bottom so it crosses out
420 cm * 1 meter / 100 cm = 4.2 meters
4600 mm
1000 mm = 1 meter
1 meter / 1000 mm = 1
4600 mm * 1 meter / 1000 mm = 4.6 meters
Therefore, our order is
420 cm, 4.3 meters, 4600 mm, 0.04 km
If x is the third side, then x is between 5-3 = 2 and 5+3 = 8. The value of x cannot be equal to 2, or it can't be equal to 8 either.
So 2 < x < 8. The following answer choices fit this inequality:
choice B) 6 cm
choice C) 4 cm
The other answer choices are outside of the interval 2 < x < 8
So that's why the answers are choice B and choice C.
