They are asking which one gives both the same answer.
Cost per pound: 50 <span>¢.
Weight: 3 pounds
Total cost: 3x50 = 150 </span>¢
The answer is C.) -4n + 11 < -9
<span>N + D = 55 coins (1) (N stands for nickels,
5N + 10D = 390 cents (2) D stands for dimes)
Simplify (2) by canceling the factor 5 in both sides:
N + 2D = 78 (3)
Subtract eq(1) from eq(3). You will get
D = 78 - 55 = 23.
Answer. 23 dimes and 55-23 = 32 nickels.
Check. 23*10 + 32*5 = 390 cents</span>
6x-30 is equivalent to the expression
