Answer:
10
Step-by-step explanation:
Seeing the 5 12 13 triple you get 1/2x=5 so
x=10
A. 696 - take 1200 (the population of the school) and multiply by the result you found (.58 or 58%). 1200 * .58 = 696
The answer to this equation is C, 2925 mm^2 and 29.25 cm^2.
The lines whose equation is x = a, are vertical lines that pass through the point (a, y) where y is any real number. Additionally, vertical lines have an indefinite slope.
You can see it in the graph of this equation:
