Answer:
x= -6
Step-by-step explanation:
2x/3=x+2
multiply each side by 3
2x/3*3=x+2*3
calculate
2x=3x+6
move variable to the left and change the sign
2x-3x=6
collect like terms
-x=6
change the signs
x= -6
We're given the hypotenuse and one side and we're looking for the missing side so use pythagorean.
20² - 16² = 144²
Square root of 144 = 12 feet
Add them all up.
A triangle has 3 sides, and you said each side is 3. So:
3+3+3 = 9
Step one: Do half of 28. So now you know what one hour is okay.
Step two: You now know three hours is 42 stops
Step Three: total amount in 4 hours 28 times 2 and that is 56 stops
