Answer:
2
Step-by-step explanation:
The scale factor is 2 because every aspect of figure a doubled.
First let's define variables:
r: reading
s: skimming
We write the system of equations that adapts to the problem:
r + s = 275
(15/10) r + (10/15) s = 355
We solve the system of equations:
r = 206
s = 69
Note: see attached image for system solution.

Answer:
33 meters
51 meters
Step-by-step explanation:
84-18= 66
66/2= 33
33+18= 51
Check your answer:
51+33=84
Surface area of the pyramid= 4*(area of the triangle) + area of the square
Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²
Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
