Answer:

x = 14

Angle B = 121°

Angle C is 59°

Step-by-step explanation:

First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)

10x-19 = 7x+23 subtract 7x

3x-19 = 23 add 19

3x = 42 divide by 3

x = 14

Angle B is 10x-19, and if x=14, then its 10(14)-19

Angle B is 140-19

which is 121°

Angle B = 121°

Angle B and Angle C add up to 180°

121° + c = 180°

c = 180-121

Angle C is 59°

Answer:

$- 28 - \frac{1}{5} n = \frac{3}{5} n \\ - 28 = \frac{1}{5} n + \frac{3}{5} n \\ - 28 = \frac{4}{5} n \\ n = \frac{( - 28) \times 5}{4} \\ n = ( - 7) \times 5 \\ \boxed{ n = - 35}$

<u>n=-35</u> is the right answer.

Which method would be the simplest way to solve the system?

Lunna [17]

It would be elimination (C) because 7x and -7x can be eliminated into 0.

  7x + 5y = 19
  -7x - 2y = -16
  3y = 3
3 3
  y = 1
  7x + 5y = 19
7(1) + 5y = 19
7 + 5y = 19
- 7 - 7
5y = 12
5 5
y = 2.4
  (x, y) = (1, 2.4)
