Answer:
Step-by-step explanation:
n and d are the number of nickels and dimes, respectively.
"there are 20 coins"
n+d = 20
d = 20-n
"total value is $1.40"
0.05n + 0.10d = 1.40
0.05n + 0.10(20-n) = 1.40
-0.05n + 2 = 1.40
0.05n = 0.6
n = 12
d = 20-m = 8
Answer:
x = 1/2 or x = -4
Step-by-step explanation:

2x - 1 = 0 or x + 4 = 0
2x = 1 or x = -4
x = 1/2 or x = -4
