join sentences together. serena lives in an apartment. it is on the first floor. a. and b. or c. but d. as if

To join these, you need to use the correct coordinating conjunction. Those are the FANBOYS (for, and, nor, but, or, yet, and so). Therefore, ‘as if’ doesn’t work. While or and but are choices, they do not correctly or accurately depict the information. The best answer is ‘and’. Serena lives in an apartment, and it is on the first floor. A

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
