Ok, so I'm pretty sure you get it by just dividing 168 by 182 to get 0.923 etc. Then if you multiply it by 100 then you get your grade. Which is about a <em>92.3%</em>. Hope this helps.
Answer:
subtract by -2 on both side
-4x+2-2>-14-2
-4x>-16
dividing by -4 on both side
-4x/-4>-16/-4
then
x>4
A^2 +b^2 = c^2
a= wall
b = ground (18)
c = ladder (25)
a^2 + 18^2 = 25^2
a^2 + 324 = 625
a^2 = 301
a = 17.349
C) x=4 is the answer
2*4-1=7
8-1=7
