Answer:
2(4+x)
Step-by-step explanation:
"Twice the sum of" tells us it will be the equation times two
"the sum of four and a number" is easy, thats 4 + x
The second number is x because the number is not specified so we need a place holder, x in this case, to tell us that the number is not given.
All this put together = twice the sum of four and a number, or <u>2(4+x)</u>
The answer is the first one
(n - 2)*180
Therefore, (8 - 2)*180
Which equals to 6(180) or 1080
Hope this helps! :)
Answer:
Step-by-step explanation:
Reasoning A store sells packages of comic books with a poster. A poster and 5 comics cost $13.99. A poster and 12 comics cost $20.99. Write a linear function rule that models the cost y of a package containing any number x of comic books. Suppose another store sells a similar package, modeled by a linear function rule with initial value $. Use pencil and paper. Explain which store has the better deal. The linear function rule is y nothing.
