Mathematics

Answer:

  (x, y) = (2, 5)

Step-by-step explanation:

Double the second equation and subtract the first:

  2(7x +y) -(3x +2y) = 2(19) -(16)

  11x = 22

  x = 2

In the second equation, ...

  7(2) +y = 19

  y = 19 -14 = 5

The solution is (x, y) = (2, 5).

Vertical angles are formed when two lines intersect, and two angles that are on opposite sides of both lines.

The angles on the west side and the east side form two vertically opposite angles (commonly called vertical angles, but much less descriptive).
It is because the west angle is to the left of both lines, and the east angle is to the right of both lines.

Vertically opposite angles (vertical angles) are congruent.  Therefore we can form the equation
110 = 5x
Divide both sides by 5 to get
110/5=22 = 5x/5 = x
or 
x=22 degrees.

to make an apple pie, mimi needs 2 cups of flour and 3 cups of apples. how many cups of ingredients does mimi need to make 5 pie
Lady_Fox [76]
For one apple pie, Mimi needs 2 cups of flour and 3 cups of apples, which is 5 cups in all, in order to produce how many cups she would need to make five pies you simply times the number given, number of cups, by 5. So you times 2 by 5, which is 10 and 3 by 5, which is 15 and together that makes 25 cups, 10 cups of flour and 15 cups of apples. If you had three cups of flour and needed to make 20 pies, all you would do is times three by 20, which is 60. 

Hope I explained this correctly, if you need any more help, please ask.
