Answer:
Step-by-step explanation:
Let the number of dimes be d and quarters be q
<u>The value is $8.80 = 880¢, so:</u>
- 10d + 25q = 880 ⇒ 2d + 5q = 176
<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>
- 25d + 10q = 730 ⇒ 5d + 2q = 146
<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>
- 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
- 4d - 25d = -378
- -21d = -378
- d = -378/-21
- d = 18
Answer:
Federalists wanted a
centralized banking
system and Alexander
Hamilton, as Secretary of
the Treasury, proposed a
national bank in 1789.
• Antifederalists, like
Thomas Jefferson,
opposed this plan.
– They favored a
decentralized banking
system in which states
established and
regulated banks within
their borders.
Step-by-step explanation:
You can isolate y on both sides, getting:
2x-17=y and x-10=y
Then, make the two y equal each other, and solve the equation
2x-17=x-10
The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T
Therefore, the answer is x=7 and y = -3, or (7,-3)
