Solve the equation -5(x-2)=-(x+6)

Answer:

X= -8

Step-by-step explanation:

Subtract 6 on both sides

that leaves you with

5/5=-40/5 The 5s cancel out leaving you with -40/5 and -40 divided by 5 is -8

Answer:

x= -8

Step-by-step explanation:

5x - 6 = -46 original equation

5x = -40 added 6 to both sides

[tex]\frac{5x}{5} = \frac{-40}{5}[/tex] divide both sides by 5

x = -8 solution

marked price = $1200

discount % = 30%

selling price = ?

so,

SP = MP - D% of MP

= $1200 - 30% × 1200

= $1200 - 360

= $840

Answer:

The answer is 50 squared.

Explanation:

This number is the only irrational number given.

The value of the expression 3x + 2y when x =6 and y =7 is 32.

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

As per the given expression, 3x + 2y

Put x = 6 and y = 7 as,

3(6) + 2(7) = 18 + 14 = 32

Hence "The value of the expression 3x + 2y when x =6 and y =7 is 32".

Slope intercept is:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept.

The slope in the question is -12. The y-intercept is 1/2.

Plug in the values:

[tex]y=mx+b\rightarrow \boxed{y=-12x+\frac{1}{2}}[/tex]

Hope this helps.

Answer:

Slope-intercept form:

[tex]y = -12x + \frac{1}{2}[/tex]

Step-by-step explanation:

-Since you already have the slope and the y-intercept, all you need is to apply them to a slope-intercept form:

Slope: [tex]-12[/tex]

y-intercept: [tex]\frac{1}{2}[/tex]

-Slope-intercept equation:

[tex]y = mx + b[/tex]

(where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)

-Applying to slope-intercept form:

[tex]y = -12x + \frac{1}{2}[/tex]

5 by 3

Explanation:

15 = 5 x 3

16 = 5 + 5 + 3 + 3

The dimensions of the board is either 5 by 3 square inches or 3 by 5 square inches.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

here,
let the length of the board be x, and width be w,
The perimeter of the rectangle board  = 16
2 (l + w) = 16
l + w = 8
l = 8 - w

Now,
area of the board = 15
l × w = 15
(8 - w)w = 15
8w - w² = 15
w² -8w + 15 =0
(w - 3)(w -5) = 0
So,
w = 3 or 5
Now,
Lengths = 8 - 3 or 8 - 5
              =  5 or 3

Thus, the dimension of the board either 5 by 3 square inches or 3 by 5 square inches.

Answer:

27 chickens

Step-by-step explanation:

A chicken farmer also has cows for a total of 30 animals

Both animals have a total of 66 legs

Let a represent the number of chicken

Let b represent the number of cows

a + b= 30........equation 1

Since a chicken has only two legs and a cow has four leg then, the expression can be represented as

2a + 4b= 66........equation 2

From equation 1

a + b= 30

a = 30-b

Substitute 30-b for a in equation 2

2a + 4b= 66

2(30-b) + 4b= 66

60 - 2b + 4b= 66

60 + 2b= 66

2b= 66-60

2b= 6

b= 6/2

b= 3

Substitute 3 for b in equation 1

a + b = 30

a + 3=30

a= 30-3

a= 27

Hence the farmer has 27 chickens

Answer:

a = -21

Step-by-step explanation:

-3a +2a -8 = 13

- a-8 = 13

-a -8 -13 = 0 ( the sign changes from +13 to -13 )

-8 -13 = a ( the sign of a changes from -a to + a ) -21 = a

Answer:

10, 4, 8

Step-by-step explanation:

This equation here is shown in the form of [tex]y = x-4[/tex]. However, we are solving for x when we know y. I find it easier to convert the equation so we have [tex]x = ...[/tex]. To do this we can add 4 to both sides.

[tex]y + 4 = x, x = y+4[/tex].

Now that we know our equation ([tex]x = y+4[/tex]), we can substitute the values of y inside to find x.

[tex]x = 6+4\\\\x = 10[/tex]

[tex]x = 0+4\\\\x = 4[/tex]

[tex]x = 4+4\\\\x = 8[/tex]

Answer:

-25

Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25.

Answer:

y = -2x + 22

Step-by-step explanation:

You fill an aquarium with water, the water is 22 inches deep. The water evaporates at 2 inches per week. Write an equation that approximates the depth y of water in the aquarium x weeks after you fill it.

Answer: The problem above represents that of a linear function. The equation of a linear function is given by:

y = mx + b, where y is the dependent variable, x is the independent variable, m is the rate of change and b is the initial value of y when x = 0.

From the problem, the independent variable is the number of weeks and the dependent variable is the depth of water, hence y = depth of water and x = weeks after you fill it.

The rate = 2 inches per week, since it evaporates (decreases), hence m = rate of change = -2. Also, at 0 weeks (x = 0), the depth (y) = 22 inches, therefore b = 22. Using the equation for linear function, we get:

y = -2x + 22
