Answer:

Step-by-step explanation:

since BD and BC are congruent, angle C and angle D are equal. this means 6x-9=3x+24. If you solve this equation you get x=11. If you plug it into either 6x-9 or 3x+24 you get 57. 180-(57+57)=66

3. A rabbit and turtle are in a race. Is the relationship between distance

frutty [35]

Answer:

The relationship is proportional for the turtle and the equation is Distance = 54*Time

Step-by-step explanation:

Turtle’s run:

Distance (meters) | Time (minutes)

108 | 2

405 | 7.5

540 | 10

1768.5 | 32.75

Rabbitt’s run:

Distance (meters) | Time (minutes)

800 | 1

900 | 5

1107.5 | 20

1524 | 32.5

The relationship between distance traveled and time is proportional if this equation is satisfied:

Distance = k*Time or k = Distance/Time

where k is a constant

For the turtle:

108/2 = 405/7.5 = 540/10 = 1768.5/32.75 = 54

Then, the relationship is proportional and the equation is Distance = 54*Time

For the rabbit:

800/ 1 = 800

900/5 = 180

1107.5/20 = 55.375

1524/32.5 = 46.89

Then, the relationship is not proportional.

Solve for x: |2x+6| -4 = 20

Bingel [31]

|2x + 6| - 4 = 20

First, add 4 to both sides. / Your problem should look like: |2x + 6| = 20 + 4
Second, simplify 20 + 4 to 24. / Your problem should look like: |2x + 6| = 24
Third, break down the problem into these 2 equations. / 2x + 6 = 24 and -(2x + 6) = 24
Fourth, solve the 1st equation: 2x + 6 = 24
Subtract 6 from both sides. / Your problem should look like: 2x = 24 - 6
Simplify 24 - 6 to 18. / Your problem should look like: 2x = 18
Divide both sides by 2. / Your problem should look like: x = $\frac{18}{2}$
Simplify $\frac{18}{2}$ to 9 / Your problem should look like: x = 9
Fifth, solve the 2nd equation: -(2x + 6) = 24
Simplify brackets. / Your problem should look like: -2x - 6 = 24
Add 6 to both sides. / Your problem should look like: -2x = 24 + 6
Simplify 24 + 6 to 30. / Your problem should look like: -2x = 30
Divide both sides by -2. / Your problem should look like: x = $\frac{30}{-2}$
Simplify $\frac{30}{-2}$ to $- \frac{30}{2}$ / Your problem should look like: x = $-\frac{30}{2}$
Simplify $\frac{30}{2}$ to 15. / Your problem should look like: x = -15
Sixth, collect all of your solutions. / Your problem should look like: x = -15, 9

Answer: x = -15, 9 (C)
