your endpoints are correct, however recall that x² means (x)².

Answer:
-2 2/5
Step-by-step explanation:
- 3/5 + - 9/5 = -12/5
-12/5 = -2 2/5
Answer:Number of coins that are quarters =60
Step-by-step explanation:
Total coins in possession of Eric=240
Number of coins that are pennies=11\20 x 240= 132
Number of coins that are nickels=4\20 x 240= 48
Since the rest are quarters,
Number of coins that are quarters =Total coins in possession of Eric -( Number of coins that are pennies+ Number of coins that are nickels)
=240-(132+48)
=240-180
=60
(1,1) because x + 2y <4
=1 + 2(1)
= 3 which is less than 4
