Answer:

40y+20=60y-40

60y-40y=20+40

20y=60

y=60÷20

y=3

8x=2x+30

8x-2x=40

6x=30

x=30÷6

x=5

(40×3+20) = 140

8×5 = 40

(2×5+30)=40

(60×3-40)=140

Answer:

y = 3

x = 5

Step-by-step explanation:

40y + 20 = 60 y - 40 because opposite angles are equal

solve this equation

40y + 60 = 60 y

60 = 20 y

3 = y

8x = 2x +30

6x = 30

x = 5

If the following system of equations was written as a matrix equation in the form AX = C, and matrix A was expressed in the form

IrinaVladis [17]

Answer: a-b+c+d =4

Step-by-step explanation:

The given system of equation is

$2x+8y=7\\4x-2y=9$

from this we have the following matrices

$A_1 =\begin{bmatrix}\\2 &8 \\ \\4&2 \\\end{bmatrix}\ ,X=\begin{bmatrix}\\x\\ \\y\\\end{bmatrix}\text{and}\ C=\begin{bmatrix}\\7\\ \\9\\\end{bmatrix}$

the given matrix A = $\begin{bmatrix}\\a &c \\ \\b &d \\\end{bmatrix}$

On comparing Matrix $A_1$ with Matrix A

$\begin{bmatrix}\\a &c \\ \\b &d \\\end{bmatrix}=\begin{bmatrix}\\2&8 \\ \\4 &-2 \\\end{bmatrix}$

we have the following values

a=2 ,b=4,c=8,d=-2

Thus a-b+c+d =2-4+8+(-2)=4

Answer:

Option G

Step-by-step explanation:

Option F

m∠1 + 121 = 180 [Sum of linear angles = 180°]

True.

Option G

121 + m∠2 + 33 = 180

False. Because 121° is not an interior angle of the given triangle.

Option H

33 + m∠1 = 92

True.

Measure of exterior angle of a triangle is equal to the sum of he measure of the non adjacent interior angles.

Option J

121 + 92 + m∠3 = 360°

True.

Sum of the exterior angles of triangle is 180°.
