Atropical storm becomes a hurricane when wind speeds reach 50 km/hr.

False

Explanation:

Hurricanes are the heavy storms that form over the ocean in the places where there is warm water. They catch this warm water energy and draws it to the atmosphere and water vapor also is present. Along with these, the wind also is necessary that blows gently high up towards the atmosphere and also it blows strongly near the surface region on earth. Due to these, the strong wind rotates at a considerably faster rate which ultimately forms a hurricane.

Generally, a typical storm that blows below the speed of 70-75 mph is considered as the tropical storms but if it exceeds this speed then they are considered to be a hurricane. Hurricanes are very violent storms and cause huge damage.

Thus, the above statement is false.

the answer is d (apex) good luck : ))

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
