90 cars out of 450
90 / 450 = 1/5
I guess the number of floors is 5

Answer:
x+6=y and 3x=12
Step-by-step explanation:
Let x be the distance traveled by Bryan and let y be the distance traveled by Sam then the first equation would be:
x+6=y (x plus 6 is equal to y, Bryan's distance plus 6 is equal to Sam's distance) and the second one is:
3x=12 (3 times x is 12, 3 times the distance travelled by Bryan is 12)
So our statements/equations are:
x+6=y and
3x=12 (we dont write this as x=4 as it asks us to give the statements we got from the information given, we only start simplifying once it tells us to solve)
The dilation by a scale factor of 1.8 means that every x and y coordinate are multiplied by 1.8 converting x,y into 1.8x, 1.8y.
This kind of transformation results in a similar figure.
So the triangle A'B'C' will be similar to triangle ABC: which means that all the angles are preserved (thy are congruent).
Being the angles congruent the slope of B'C' will be the same angle of BC.
Since, the slope of AB is - 1, the other two sopes are one 0 and the other undefined (∞). The horizontal side has slope 0 and the vertical side has slope ∞.
Since you did not attache any figure I do not know whether B'C' is the horizontal or the vertical side.
The answer is that the slope of B'C' is zero if it is the horizontal side, and the slope is ∞ if B'C' is the vertical side.
