Music is an important element of a student’s education. one study says that schools with music programs had graduation rates of about ninety-three percent. in schools without music programs, the graduation rate dropped to around seventy-two percent.
what is the best transition to add at the beginning of the third sentence?
conversely,
finally,
similarly,
specifically,

The correct answer is A. Conversely,

Explanation:

In writing, the transitions are words or phrases added to connect ideas and explicitly express the relationship between them, because of this, the transition used depends on the type of relationship between the ideas being connected. In the case presented, a transition is needed to connect the third sentence "In schools without music programs, the graduation rate dropped to around seventy-two percent" to the two previous ides and considering the first idea deals with the importance of music and the second idea explains schools with music programs had high graduation rates, the transition use should be a transition of contrast and from the options provided the only one that shows contrast is "Conversely,". Therefore, the transition that needs to be added is "conversely," because this stablishes the contrasting relationship between the two first sentence and the last third sentence.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
