-4x -6 = 3 - 5x<br> Solve for x pls
ycow [4]

Answer:

x = 9

Explanation:

  • -4x - 6 = 3 - 5x
  • Add 6 to both sides

-4x - 6 + 6 = 3 - 5x + 6

-4x = -5x + 9

  • Add 5x to both sides

-4x + 5x = -5x + 9 + 5x

  • x = 9

Oksanka [162]

Answer:

About 36%.

Step-by-step explanation:

The formula for the rate of return on investment is the total value minus the initial cost divided by the initial cost.

The total value is $1,500. The initial cost is $1,100.

(1,500 - 1,100) / 1,100 = 400 / 1,100 = 4 / 11 = 0.363636363636

So, Dean's rate of return on investment is about 36%.

Hope this helps!
