An example of commerce that would be regulated by the federsl government is A. A ferry that takes passengers from New York to New Jersey.
B. A bakery that sells homemade bread in Texas.
C. A company that rents paddle boats on a lake in Florida.
D. A bus that takes passengers between two towns in Missouri.

A company that rents paddle boats on a lake in Florida.

Explanation:

Taking people somewhere is just a tour from one destination to another. It has nothing to do with a bus or ferry taking people places (A and D are out of the question)

A bakery that sells homemade bread in Texas is just a homemade local shop in Texas. It has nothing to do with commerce.

On the other hand, renting a paddle boat is a true source of commerce

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
