Solve with steps please giving brainliest <br><br> -5x-16=9x+x-1
creativ13 [48]

Answer:

x = - 1

Step-by-step explanation:

- 5x - 16 = 9x + x - 1

- 5x - 16 + 16 = 9x + x - 1 + 16

- 5x = 9x + x - 1 + 16

- 5x = 10x + 15

- 5x - 10x = 10x - 10x + 15

- 15x = 10x - 10x + 15

- 15x = 15

- 15x ÷ - 15 = 15 ÷ - 15

x = 15 ÷ - 15

x = - 1

Zinaida [17]

Answer:

4.99 + 1.99m = T. Dependent Variable = T (Total Cost), Independent Variable = M (Movies) Now, for the equation we have to input 5 for the m because he watched 5 movies. So, 4.99 + 1.99(5) = T Well, 1.99 x 5 is 9.95 so our next step is this 4.99 + 9.95 = T and that  added up together would be 14.94 dollars. $14.94 = T

Step-by-step explanation: I hope that this helps you!
