What is the value of x in the equation x-2/3 + 1/6 =5/6 ?

X is a negative one (-1). The negative one makes it so that the -2/3 is a positive when they multiply.

So in this problem we can see that 2 out of 3 of the fractions have a denominator of 6. One of the fractions (2/3) has a denominator of 3. But we can make the denominator 6 by multiplying it by 2!

Now the equation is:

x - 4/6 + 1/6 = 5/6

So now let's solve for x!

x - 4/6 + 1/6 = 5/6

x + 1/6 = 9/6        (Addition property of equality)

x = 8/6                 (Subtraction property of equality) 

Now we divide...

8 divided by 6 equals 1.33

Now if we plug that into the equation as 1 and 1/3...

1 and 1/3 - 2/3 + 1/6

2/3 + 1/6

4/6 + 1/6 = 5/6

So that means your answer is decimal 1.33 or mixed fraction 1 and 1/3

Find the speed of the Scooter in miles/hr.
Speed = distance/time
Distance = 21.98 inches = 0.00034548611miles
Time = 10 seconds = 0.00277778 hrs.

Speed = 21.98/10
Speed = 2.198 inches/seconds
or
Speed = .12miles/hr.
