-2/3x+9=4/3x-3 original problem add 2/3x to both sides
9=6/3x-3 simplify 6/3 to 2 and add 3 to both sides
12=2x divide both sides by 2
x=6
hope that helps
Here is the correct order of the step:
Identify: Anna's time is the unknown
Strategize : let x = Anna's time
Set up : 7(40) = x(50)
Solve: x = 5.6
Check: 7(40) = 5.6(50)
<h3>What is Anna's time?</h3>
The first step is to determine the distance Allen travelled:
Distance = average speed x time
40 x 7 = 280 miles
The second step is to determine the time it took Anna to travel 280 miles.
Time = distance / average speed
280 / 50 = 5.6 hours

Answer:
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)
Step-by-step explanation:
We know that the volume of a rectangular prism is the product of its base area and height
Volume_prism = area_base * height
height = Volume_prism / area_base
Volume_prism = (x^3 – 3x^2 + 5x – 3)
area_base = (x^2 – 2)
height = Volume_prism / area_base
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)

Answer:
m∠1 = 81
m∠2 = 99
Step-by-step explanation:
The angles are supplemaentary and therefor sum to 180
3x + (x + 72) = 180
4x + 72 = 180
4x = 108
x = 27
m∠1 = 3x
m∠1 = 27(3)
m∠1 = 81
m∠2 = x + 72
m∠2 = 27 + 72
m∠2 = 99
