Answer:
Prism
B- A triangle cannot be "two polygons"
C- A cube also cannot be "two polygons"
D- A pyramid is not parallel.
We have 3x+50=6x-10 subtracting 3x from both sides we get 50=3x-10. Now we add 10 to both sides to get 60=3x. Dividing both sides by 3 we get x=20.
Answer:
Casey Bought 6 bags of chips
Step-by-step explanation:
If each sandwich costs 3 times the amount of a bag of chips and the sandwich is 6 dollars, the chips are 2 dollars. Casey bought 5 sandwiches and spent $30 dollars on sandwiches. Since the total was $42 dollars you have $12 dollars left to get your total of $42. 2x6 = 12 so therefore Casey bought 6 bags of chips.
