Answer:

X=-5

X=-7

Step-by-step explanation:

-12x+(-4)=56

rewrite the equation to -12x-4=56

add 4 to both sides

-12x=60

Divide by -12 on both sides

x=-5

-2.1x+(-3.9)=10.8

-2.1x-3.9=10.8

-2.1x=14.7

divide by -2.1 on both sides

x=-7

Answer: x=5

Step-by-step explanation:

To find the value of x, we set the measures of 1 and 5 equal to each other.

3x+7=5x-3        [subtract both sides by 5x]

-2x+7=-3           [subtract both sides by 7]

-2x=-10             [divide both sides by -2]

x=5

Now, we know that x=5.

Answer:

i got 14.52 as the unit price, Is there some sort of tax or extra expense not included with your question?

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Using order of operations, we have to divide 32 by 8 first since its in parentheses, then add and subtract from left to right, so: (32/8)+27-11 = 4 + 27 - 11 = 31 - 11 = 20

Answer: 49 50 51 ?

Step-by-step explanation:

Answer:

49

Keep adding 1

Answer:

89

Step-by-step explanation:

The sum of the angles in a triangle is always 180 degrees. So if you add 50 and 41 together, you get 91. 190-91= 89 degrees.

Answer:

[tex]y=\frac{3}{2} x+5[/tex]

Step-by-step explanation:

subtract 6x

-4y = -6x + 20

divide by -4

[tex]y=\frac{3}{2} x+5[/tex]

Answer:

y= 3/2x-5

Step-by-step explanation:

Slope intercept form means to solve for y. So,

6x-4y=20 (Subtract 6x)

-4y=-6x+20 (Divide by -4)

y= 3/2x-5

Answer:

y = 1/4x + 1.5

Step-by-step explanation:

To solve a problem like this we can use the formula y - y1 = m(x - x1), in which y1 is the y coordinate, x1 is the x coordinate, and m is the slope.

Equation:

y - 1 = 1/4(x + 2)

y - 1 = 1/4x + 0.5

y = 1/4x + 1.5

Answer:

[tex]y=\frac{1}{4}x+\frac{3}{2}[/tex]

Step-by-step explanation:

A line has the following equation

[tex]y=mx+b\\\\\longrightarrow m=slope\\\\m=\frac{1}{4}\:given\\\\\longrightarrow b= constant\\\\\Rightarrow y=\frac{1}{4}x+b\\\\(-2,1)\rightarrow\:x=-2,\:y=1\\\\(1)=\frac{1}{4}(-2)+b\\\\1=-\frac{1}{2}+b\\\\b=1+\frac{1}{2}\\\\b=\frac{2}{2}+\frac{1}{2}\\\\b=\frac{3}{2}\\\\\Longrightarrow y=\frac{1}{4}x+\frac{3}{2}[/tex]

Answer:

X=-4

Step-by-step explanation:

Answer:

the answer would be B: 4x=3y

Step-by-step explanation:

this is perimeter which means that you add the side lengths all together.

5x-3y+x+4y-2x+2y

then you just add the like terms

Answer:

b) 4x + 3y

Step-by-step explanation:

add all equations (perimeter = side + side + side)

P= 5x-3y + x+4y -2x+2y

combine like terms

5x + x - 2x = 4x and -3y + 4y + 2y = 3y

P = 4x + 3y

Answer:

y = 50

Step-by-step explanation:

Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.

Now, just plug x into the equation.

y = 5(10)

y = 50

i can help but you need to explain the question

Step-by-step explanation:

Answer:

Janie is 12

Chad is 15

Step-by-step explanation:

27 - 3 = 24

24 : 2 = 12

12 + 3 = 15 (Chad)

27 - 15 = 12 (Janie)

Janie is three years younger than her brother Chad and she is 12 years old

Janie is 3 years younger than her brother Chad.

let

Chad age = x

Janie age = x - 3

The sum of there ages is 27. Therefore,

x + x - 3 = 27

2x - 3 = 27

2x = 30

divide both sides by 2

x = 30 / 2

x = 15

Chad age = 15 years

Janie's age = 15 - 3 = 12 years
