So 22 problems/ 30 minutes = ? problems/ 180 minutes
so you basically just convert them
and you will times 30 by 6 to get 180, so you times 22 by 6
and you will get 132 problems
so Koby can do 132 problems
So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).
So (paper rock) scissors= paper scissors = scissors,
But paper (rock scissors)= paper rock = paper.
This is a good example because it shows that associativity matters even outside of math.
All the triangles have 180° total angle measurement.
First question:
114 + 37 + x = 180°
151 + x = 180
x = 180 - 151
x = 29°
Second question:
93 + 46 + x = 180
139 + x = 180
x = 180 - 139
x = 41°
