Answer:
2x+3x-15=180°
Step-by-step explanation:
When two angles are supplementary, their angles would equal to 180° total when added together. In this answer, the two angles are added together to create 180°.
You divide by 5/13. Remember when dividing fractions you multiply by the reciprocal. 5/13 cancels on the left side, leaving t.
So here you have -9/(5/13), but we can put -9 as -9/1, then instead of dividing by 5/13, multiply by 13/5: 117/5. This evens out, when divided, to t=23.4
Answer:
7/6
Step-by-step explanation:
You have correctly graphed the line, so you know that the rate of change is ...
∆d/∆t = 7/6
d changes by 7/6 units for each unit change in t.
