Each week, Nia takes a violin lesson and a dance lesson. The dance lesson costs as much as
the violin lesson, and the cost of both lessons combined is $75. Which of the following systems
of equations could be used to find d, the cost of the dance lesson in dollars, and v, the cost of
the violin lesson in dollars?

To solve for the costs of Nia's dance and violin lessons, we use the system of equations d = v and d + v = 75, where d is the cost of the dance lesson and v is the cost of the violin lesson.

The question involves finding a system of equations to determine the costs of a dance lesson (d) and a violin lesson (v) for Nia, where each of the lessons costs the same, and their combined cost is $75. From the information given, we can derive two equations. The first equation is based on the equality of the cost of the dance lesson and the violin lesson, which gives us d = v. The second equation comes from the total cost of both lessons being $75, therefore d + v = 75. These two equations together form the system that can be used to solve for the values of d (cost of the dance lesson) and v (cost of the violin lesson).

Which one of these is a disadvantage to tax-paying individual investors?

Pigs are curious animals thought to be more intelligent than an average three-year-old human child. They are smarter than dogs and every bit as friendly. They are also loyal and affectionate. When in their natural surroundings, they are social, playful, and protective animals. They bond with each other and make beds. They like to relax in the sun and cool off in the mud.
Most people are not that familiar with pigs. You may be surprised to learn that they dream and recognize their names. They play video games better than some primates, like monkeys and apes. They also lead social lives as complicated as the lives of primates.
People who run animal shelters often describe pigs as having human characteristics. They've learned that pigs enjoy listening to music and playing with soccer balls. They even love getting massages!
