Solve 7x - 12 = k for x
shtirl [24]

Answer:

x = 1/7(k+12)

Step-by-step explanation:

7x - 12 = k

Add 12 to each side

7x = k+12

Divide each side by 7

7x/7 = (k+12)/7

x = 1/7(k+12)

The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at
satela [25.4K]
The total cost is the dependant variable and the number of tickets along with flat out price is the independent variable.

The equation would be y = 1.25x + ?

You would insert 25 for x which equals 31.25 and insert 43.75 for y.

43.75 = 31.25 + ? Then subtract 31.25 from both sides of the equation and you would get....

12.5 = ?

That is your flat rate to get in to the fair
