B. 6-4-(-5)
C. 6-(4+5)
D. 6+4-5
E. -(-6) + (-4) – (-5)

Answer:

x,y,z=4,3,-4

Step-by-step explanation:

2x+4y-6x=44   =    x+2y-3z=22

x+2y-3z=22

x+2y+3z=-2

x+2y-3z=22

3x-4y+4z=-16

x+2y-3z=22         ------>

                                         2x+4y=20

x+2y+3z=-2          ------>

x+2y-3z=22                      ------>

                                                        13x-4y=40

3x-4y+4z=-16                    ------->

2x+4y=20

13x-4y=40

y=3

x=4

4+2x3-3z=22

z=-4

(x,y,z)=(4,3,-4)

2x4+4x3-6x(-4)=44

4+2x3+3x(-4)=-2

44=44

-2=-2

-16=-16

(x,y,z)=(4,3,-4)

I am so sorry if it is incorrect I  tried :<

Step-by-step explanation:

let amount of money for cheese scone be x

plain scone is 3x and fruit scone is 4x add them all up and it is 8x

96/8 is 12

then that means x=12 and plain scone is 12 times 3 which is 36

Answer:

the answer is 60/100 60%

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

1. (x + 6)(x - 4)

x (x - 4) + 6 (x - 4)

x² - 4x + 6x - 24

x² + 2x - 24

2. (2x + 5)(x - 3)

2x (x - 3) + 5 (x - 3)

2x² - 6x + 5x - 15

2x² - x - 15

3. (3x + 2)(2x + 5)

3x (2x + 5) + 2 (2x + 5)

6x² + 15x + 4x + 10

6x² + 19x + 10

4. (2x - 1)(x - 5)

2x (x - 5) + -1 (x - 5)

2x² - 10x + -x + 5

2x² - 10x - x + 5

2x² - 11x + 5

Answer:

160 pins

Step-by-step explanation:

Answer:

A) supplementary

B) 148°

C) 50°

Step-by-step explanation:

A) supplementary

B) 180-32=148

C) 90-40=50

Answer:

52° and 128°

Step-by-step explanation:

The sum of the angles in a triangle is 180°

So to find the angles, the easiest thing to do is to use that fact.

There is one angle missing in the triangle shown, so to find it you need to subtract (5x-2)° from 180° since the angle is located on a line.

Simplifying that, you get 180°-(5x-2)°.

Now you can use the fact at the top of these instructions.

So you get the equation: 180°=2x°+76°+180°-(5x-2)°

Solving this equation, you get x=26

Plug x into the values that have x in the picture, and you get 52° and 128°

Here the height and length are the sides of the rectangular wall and we have to find the area.

Area of rectangle is given by:

[tex] = l \times b[/tex]

where l is the length and b is the breadth/width according to the question. Plugging the given values:

[tex] = 110 \times 96 \: {inch}^{2} [/tex]

[tex] = 10560 \: {inch}^{2} [/tex]

The area of the wall is 10560 inch²

Step-by-step explanation:

[tex] \underline{ \underline{ \text{Solution}}} : [/tex]

[tex] \sf{4x - 3y = 19}[/tex] ••••• equation ( i )

[tex] \sf{2x + 3y = 23}[/tex] ••••• equation ( ii )

The coefficients of y are the same in both equation but the sign of 3y of equation ( i ) differs from the equation ( ii ). So , we add one equation from the other to eliminate 3y.

Adding equation ( i ) and ( ii ) , we get :

[tex] \sf{4x \: \cancel{ - 3y}} = 19[/tex]

[tex] \sf{2x \: \cancel{ \: + 3y}} = 23[/tex]

_________________

[tex] \sf{6x \: \: \: \: \: = \: \: \: 42 }[/tex]

Solve for x :

⟿ [tex] \sf{ \frac{6x}{6} = \frac{42}{6}} [/tex]

⟿ [tex] \boxed{ \sf{x = 7}}[/tex]

Now , substituting the value of x in equation ( ii ) , we get ( Remember : you can substitute the value of x in any of the equation ) :

[tex] \sf{2x + 3y = 23}[/tex]

⟿ [tex] \sf{2 \times 7 + 3y = 23}[/tex]

⟿ [tex] \sf{14 + 3y = 23}[/tex]

⟿ [tex] \sf{3y = 23 - 14}[/tex]

⟿ [tex] \sf{3y = 9}[/tex]

⟿ [tex] \sf{ \frac{3y}{3 } = \frac{9}{3}} [/tex]

⟿ [tex] \boxed{ \sf{y = 3}}[/tex]

[tex] \red{ \boxed{\boxed{ \tt{☥ \: Our \:final \: answer :x = 7 \: and \: y = 3}}}}[/tex]

Step-by-step explanation:

54 = 2 * 3³

72 = 2³ * 3²

To find the GCF of 54 and 72,

we find the highest common powers of their prime factors.

Highest common power for 2: 2

Highest common power for 3: 3²

Hence GCF of 54 and 72 = 2 * 3².

The answer is Option 2.

Answer:

b/2'3'3

Step-by-step explanation:

Answer:

We conclude that -1 = 0 is false, therefore the system of equations has no solution.

Step-by-step explanation:

Given the system of equations

y = – 4x + 6

y = – 4x + 5

solving the system of the equations

[tex]\begin{bmatrix}y=-4x+6\\ y=-4x+5\end{bmatrix}[/tex]

Substitute y = -4x+5

[tex]\begin{bmatrix}-4x+5=-4x+6\end{bmatrix}[/tex]

Refine – 4x + 5 = – 4x + 6

-1 = 0

FALSE!

NO SOLUTION!

We conclude that -1 = 0 is false, therefore the system of equations has no solution.
