What is the value of s in the equation
4(2s - 1) = 7s + 12?
a. 12
b. 16
c. 32
d. 34
can someone explain this? i think it is c. 32

The answer is B. 16  because you multiply 4 with 2s and -1 so the new equation will be 8s-4=7s+12 and you have to subtract the variable 7s to 8s the equation will be 1s-4=12 and add 4 to 12 and it gives you 16 and just divide 16 and one and you answer should be 16. :)

Both the equations must have 'Time passed after the game started' (t), as one of the key variables.

If (for a  value of t) the point  where they intersect be (), then, it does imply that  number of hot-dogs  were purchased when there was unit of time left in the football game.

Step-by-step explanation:

The linear function that represents the number of hot-dogs(x) purchased at a football game should be plotted against the variable 'Time passed after the game started' (t).

So, the equation will be ,

       x = a + bt ----------------(1) [where a ,b are constants to be found out]

The second linear function which represents the time left in the game(y) should also be plotted against 'Time passed after the game started'(t).

So the equation will be,

                   y = c + dt -------------(2) [where c ,d are constants to be found out]

If done so, if (for a  value of t) the point  where they intersect be (), then, it does imply that  number of hot-dogs  were purchased when there was unit of time left in the football game.
