Answer:

x=10

Step-by-step explanation:

Step 1: Multiply 4 with X and 3. You'll get 4x+12=x+42

Step 2: Keep the variable on one side and the number on the other side. you would subtract X and subtract 12. You'll get 3x=30

Step 3: Divide by the 3 on both sides and you'll get x=10

If an airplanes speed is 850mi/h what is it’s speed in m/s
Blizzard [7]

we are given

speed is 850mi/h

we know that

1 mile =1609.34 metre

1 hour = 3600 second

now, we can replace 1mi and 1hour

850mi/h=850*\frac{1609.34}{3600} m/s

now, we can solve it

379.98306

850mi/h=379.98306 m/s...........Answer
