Answer:

  • simplifies to -2x -17 = 5x -10
  • x = -1 . . . . the solution

Step-by-step explanation:

-2(x+5)-7=3x+2(x-5) . . . . starting equation

-2x -10 -7 = 3x +2x -10 . . . eliminate parentheses using the distributive property

-2x -17 = 5x -10 . . . . . . . . . collect terms

-7 -2x = 5x . . . . . . . . . . . . . add 10

-7 = 7x . . . . . . . . . . . . . . . . . add 2x

-1 = x . . . . . . . . . . . . . . . . . . . divide by 7

11. Rocco and Biff are two koalas sitting at the
bagirrra123 [75]

Answer:

Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Step-by-step explanation:

Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is \frac{x}{2}.

Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into 35^{0} each.

By alternate angle property,

Tan  35^{0} = \frac{\frac{x}{2} }{10}

\frac{x}{2} = Tan  35^{0} × 10

  = 7.00021

⇒       x = 2 × 7.0021

            = 14. 0042

         x = 14

Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
