Answer:
Approximately 1*10^3
Step-by-step explanation:
20,193/19=1,062
S^2 = r^2 + t^2
Also you can write it as:
S=sqrt( r^2 +t^2)
according to the choices you have
number of black pencils is 17
a) 5x - 9 = 3x + 3
5x - 3x = 3 + 9
2x = 12
x = 12 / 2
x = 6
b) x + 6 = 34 - x
x + x = 34 - 6
2x = 28
x = 28 / 2
x = 14
