Step-by-step explanation:
1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
ex: if x+9=32
subtract 9 from both sides to get rid of it
x=23
2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it
you could multiply by 3 on both sides:
x+9=69
x=60
Answer:
Step-by-step explanation:
Cosine (cos) is adjacent by hypotenuse.
In any of the 45° angles, 1 is adjacent and √2 is the hypotenuse.
So arrange them to get
Your answer will be at 300 miles, because the speed of one, and the rate of the other meet at the 300 mile mark
