Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus
Well first 9450/5=1890 then 1890/6= 315 watt hours per day
Since it follows that is a root of multiplicity 2.
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
Hey there!!
Let's take the first number as ' x '
Then, the second number would be ' x + 1 '
Sum of these = 183
Hence,
Hence, the small integer is 91
Hope my answer helps!
