Let x be the original price. Then the discounted price is
                                         discount = x(1 - 0.85)
The discounted price is $18.00. Therefore
                                         18.00 = x(0.15)
                                                 x = 18.00 / 0.15
                                                 x = $120.00
The amount she saved is $120.00 - $18.00 = $102.00

The answer to this question is that Ella saved $102.00.

Solve with a system of equations: Two angles are supplementary if the sum of their measures are 180 degrees. If one is 90 degree
julsineya [31]

Answer:

  The measures of the angles are 150° and 30°.

Step-by-step explanation:

Let x and y represent the measures of the angles, with x representing the larger angle.

  x + y = 180 . . . . . . the two angles are supplementary

  x = 90 + 2y . . . . . one is 90° more than twice the other

___

Substituting the expression given by the second equation into the first, we have ...

  (90 +2y) +y = 180

  3y = 90 . . . . . . . . . . collect terms, subtract 90

  y = 30 . . . . . . . . . . . divide by the coefficient of y

  x = 180 -y = 150

The measures of the angles are 150° and 30°.
