<span>50-8t<90
50-90<8t
-40<8t
8t>-40
t>-5
Solutions should go to the right.
Mary probably was solving it as following
</span>50-8t<90
<span>-8t<90-50
-8t<40 (here, when she divided both sides by -8, she had to change sign < to the sign >)
But she did not change the sign, and got
t<-5
</span>
Step-by-step explanation:
-5h/50 = -0.1
-1h/10 = -0.1
Multiply both sides by (10/-1)
(10/-1)(-1h/10)= (10/-1)(-0.1)
h= 1

Answer: 45 degrees</h3>
The purple arc is 315 degrees. The remaining bit (angle b) must add to 315 to get 360 degrees, which is a full rotation.
315+b = 360
b = 360-315
b = 45
