Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.
marta [7]

Answer:

Therefore the results from adding the equation in this system is

7x=-35

Step-by-step explanation:

Given:

Equations as

11x-3y=-17         .......................1

-4x+3y=-18         .......................2

To Find :

Result when adding equation 1 and 2 = ?

Solution

On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18)  as shown below

           11x     -    3y    = -17

           -4x    +   3y     = - 18

-------------------------------------------

           7x     + 0        =  - 35

---------------------------------------------

Therefore the results from adding the equation in this system is

7x=-35

Find the values of x, y, and z for which ABCD must be a parallelogram.
Rudik [331]

Answer:

A. x = 50, y = 130, z = 130

Step-by-step explanation:

50 and z are adjacent angles,

Sum of adjacent angles = 180,

50 + z = 180

z = 180 - 50

z = 130

z and x are adjacent angles,

Sum of adjacent angles = 180,

x + z = 180

130 + x = 180

x = 180 - 130

x = 50

z and y are opposite angles,

Opposite angles are equal in a parallelogram,

z = y = 130

Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year a
Anika [276]

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces
