The blueprint of a conference room is made using a scale of 3 centimeters to 1 meter. If the drawing shows the room is 27 centimeters long, how long is the actual room?

Anyone know? is appreciated! will mark brainliest if correct!

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
