Answer:
n=16
Step-by-step explanation:
take 52-4=48
take 48/3 and get 16 so n=16
Answer: 57
Step-by-step explanation:
28 1/2 / 1/2
make 28 and 1/2 into 57/2
so now 57/2 divided by 1/2
the same as 57/2 times 2/1
multiply straight across
(57)(2)/(2)(1)
114/2
57

Answer:
(b) Congruent Figures
Step-by-step explanation:
Reflections, rotations, and translations are called "rigid transformations" because they do not change the size or shape of the figure. The image is always congruent to the original.
On the other hand, dilations change the size of the figure, so the image is <em>not congruent</em> with the original.
Rigid transformations result in congruent figures.
Answer:
C. 
Step-by-step explanation:
Alan and his classmates found that the line of best fit through the data had the equation 
The slope of this line is 
If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.
The slopes of perpendicular lines are negative reciprocals of each other,
Hence that line must have slope 
Therefore we look for a line whose slope is
from the given options.
That line is the third option
