Answer:
Step-by-step explanation:
General equation of geometric sequence: 
Given:
Common ratio:
Therefore:
The answer is 140.
For every 4 toys the price increases by 20. If you divide, we find that every toy is worth 5. For example, if the amount of toys increases by 10, then the cost increases by 50. Since 20 is the closest given example being only 10 toys away, you can just add 50 onto the cost of the toys to get 140.
Answer: 3/20
Step-by-step explanation:
12/80 is simplified to 3/20
Answer:
65
Step-by-step explanation:
Total degrees in triangle: 180
Angle 1= 50
We know that the other two angles are equal, so set it as "2x"
50 +2x= 180
2x=180
x=65
