Well you are solving for Y so you have to get y by itself. So in order to do that you must multiply both sides by 3/2. You do this because you need to get 2/3 on the other side. So just multiply -12 and 2/3 and you'll get y=-18. You can check this by plugging -18 into your original equation. So 2/3y=-12 will become 2/3(-18)=-12. If the you got the correct answer then you should get -12=-12.
Wow there's a lot of questions there.
Pythagorean Theorem states that in a right triangle, the
hypotenuse^2 = leg1^2 + leg2^2
If the hypotenuse isn't known use the above formula.
If a leg isn't known, use
hypotenuse^2 = leg1^2 + leg2^2
leg1^2 = hypotenuse^2 - leg2^2
Answer:
A. 90 degrees. The diagonals of a kite are always perpendicular
B. 36 degrees. This longer diagonal of a kite bisects the angle.
C. 54 degrees. The interior angles of a triangle always add up to 180 degrees, so in triangle KHB you can do 180 - 90 - 36 = 54 degrees.
The distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
Speed = 72 km/h
time = 45 mins = 45/60 = 0.75 hours
We know,
Distance = Speed×time
Distance = 72(km/h)×0.75(h)
Distance = 54 km
Thus, the distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
