Answer:
1/2
Step-by-step explanation:
Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8
The last one is the answer
Answer:
18/5 hours or 3 3/5 hours
Step-by-step explanation:
I assume the break is at 7/5 hours.
5 hours - 7/5 hours = 25/5 hours - 7/5 hours = 18/5 hours = 3 3/5 hours
-5s-5x+5s+50 Combine like terms
5x+50
