A taxi costs 1.65 for the first mile and 0.85 for each additional mile. Which equation could be solved to find the number x of a
diamong [38]
1.65 + 0.85x= $20
           0.85x=$18.35
                 x=21 10/17 
first you write the equation 
then you have to subtract 1.65 from the equation but you also have to subtract it from 20 
then you divide 0.85 from 0.85x and from the 18.35 left over from subtracting 1.65 from 20 
then you should get x=21 10/17 (simplified) but the decimal form is a ongoing fraction so you can just round it up to the nearest hundredth

What is the average velocity between 12.00 and 15.00 seconds
bekas [8.4K]

The average between 12.00 and 15.00 seconds
can be defined in a few different ways.

Way #1:  (speed)

     Average speed =
         (1/2) (the speed at 12 seconds  +  the speed at 15 seconds) .


Way #2:  (speed)

   Average speed =
       (1/3) (the distance covered between 12.00 and 15.00 seconds)


Way #3:  (velocity)

   Average velocity =
     (1/3) (distance between location at 12 sec and location at 15 sec)
       in the direction from location at 12 sec to location at 15 sec.


That's the best we can do with the combination of given and
not given information in the question.

After using the algebraic equation, the required value of x = 55/2.

WHAT IS ALGEBRIC EQUATION?
A mathematical statement wherein two expressions have been set equal to one another is known as an algebraic equation. A variable, coefficients, and constants make up an algebraic equation in most cases. Equations, or the equal sign, simply indicate equality. Equating each quantity with another is what equations are all about. Equations act as a scale of balance. If you've ever seen a balance scale, users know that for the scale to be deemed "balanced," an equal amount of weight must be applied to each side. The scale will tip to one side if we only add weight to one side, and the two sides will no longer be equally weighted.

(x-3)2 = 49

= x-3 = 49/2

= x = (49/2) + 3

= x = 55/2

So, the required value of x = 55/2.
