Answer: Choice A</h3>
0.10d + 0.05n = 2.25
d = 2n
================================================
Explanation:
n = number of nickels
d = number of dimes
we have twice as many dimes as nickels, so we could have something like 18 dimes and 9 nickels. Algebraically we would write d = 18 and n = 9. The equation that fits this is d = 2n. The answer is between A and B at this point.
We rule out choice B since the 0.05d is incorrect. It should be 0.10d to represent the total value of all the dimes.
Choice A is correct
d = number of dimes
0.10d = value of all the dimes in dollars
n = number of nickels
0.05n = value of all the nickels in dollars
0.10d + 0.05n = total value from both coins combined
2.25 = total value from both coins combined
0.10d + 0.05n = 2.25
Answer:
x = 24
Step-by-step explanation:
T = 24.93 + 0.21x Substitute 30.18 for T
30.18 = 24.94 + 0.21x
-24.94 - 24.94 Subtract 24.94 from both sides
5.24 = 0.21x Divide both sides by 0.21
x = 24.95 ≈ 24 because you can't have a partial text message.
