Answer:

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

  -3k  -3k

19-5k= -1

-19      -19

 -5k= -20

-5/-5= -20/-5

Answer:

m = -2

Step-by-step explanation:

4 + 4{m + 1} = 0           {Subtract 4 form both sides}

   4{m + 1} = -4

   4m + 4 = -4             {Subtract 4 form both sides}  

         4m = -4 - 4

        4m  = -8             {Divide both sides by 4}

        m = -8/4

m = -2

Answer:

I think they are all always.

Step-by-step explanation:

They are called rational because they are the ratio, or quotient, of two integers

numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end and does not repeat a pattern.

The value of the expression is 130.

Here,

The values are given as;

w = 6 and x = 10

We have to find the value of expression 5w + 10x.

What is Substitution method?

The algebraic method to solve simultaneous linear equation is called Substitution method.

Now,

The values are given as;

w = 6 and x = 10

Substitute this values in given expression, we get;

5w + 10x = 5*6 + 10*10

              = 30 + 100

              = 130.

Therefore, The value of the expression is 130.

Step-by-step explanation:

Answer:

Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.

Step-by-step explanation:

We are told that his monthly profit is given by the relation;

P = 32.5x - 845

Where x is number of pictures he needs.

We want to find what the x - intercept represents.

x intercept means that the y-value at that point is zero.

Thus, x-intercept means the profit is 0.

If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.

Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.

Answer: D

Step-by-step explanation: D because if your turn 1/2 into a decimal point it 0.5 (don't forgot to add the negative) and so i then divided -0.5 from x and just got x then you have to do the same for the other side. So i took 4 and divided it by -0.5 and got -8 to the expression would be x is greater then or equal to -8. you plot the dot at -8 and the line goes in front of it because it is lesser or equal to x (remember you reverse the problem if you say it back words so don't get confused), but after my long explanation just pick D

The largest value of x that would make buying the individual card less expensive than buying the package is 57.

The total cost of buying the individual thankyou cards is the product of the cost of buying one card and the number of cards bought.

Total cost of buying the individual thankyou cards = cost per card x number of cards bought

$0.15 × x = $01.5x

The inequality equation that would be used to represent this question is

(total cost of individual thankyou cards) > cost of the package

$0.15x > $8.50

In order to determine the value of x, divide both sides of the equation by 0.15

x > (8.50 / 0.15)

x > 56.67

x > 57 to the nearest whole number

Option C. 3/4.

the slope is 3/4 for any two adjacent points.

Then use the point-slope formula y-y1=m(x-x1) where m slope and (x1, y1) point

y-1=(3/4)(x-11)

y=(3/4)x-(29/4), distributing and moving the 1 over.

A linear function is a function of the form f(x) = ax + b, where a and b are real numbers. Here, a represents the gradient of the line, and b represents the y-axis intercept (which is sometimes called the vertical intercept).

[tex]\frac{x}{3}+5=x-1[/tex]

Whenever there's a denominator. Multiply all whole equation with the denominator. For example, the denominator here in the equation is 3. So we multiply the whole equation by 3.

[tex]\frac{x}{3}(3)+5(3)=x(3)-1(3)\\x+15=3x-3[/tex]

Moving the x to the same term which goes for the same as the constant for easier in solving.

[tex]15+3=3x-x[/tex]

Moving to the another side, changing the sign/operator to opposite (From plus to minus, from multiply to divide.)

[tex]18=2x\\2x=18\\[/tex]

Move 2 to another side, aka to divide 18.

Step-by-step explanation:

The sum of the exterior angles of the n-side polygon is 360°

Let us use this rule to solve the question

∵ The given polygon has 4 sides

∴ It has 4 exterior angles, one on each vertex

→ By using the rule above

∴ The sum of the 4 angles is 360°

∵ The exterior angles are (2x + 40)°, (4x)°, (x + 50)°, and (3x)°

→ Add them, then equate the sum by 360

∴ (2x + 40) + (4x) + (x + 50) + 3x = 360

→ Add the like terms in the left side

∵ (2x + 4x + x + 3x) + (40 + 50) = 360

∴ 10x + 90 = 360

→ Subtract 90 from both sides

∵ 10x + 90 - 90 = 360 - 90

∴ 10x = 270

→ Divide both sides by 10

∴ x = 27

∴ The value of x is 27

The value of m in the inequality 28 > 4+1.5m is 16

A relationship between two expressions or values that are not equal to each other is called 'inequality.

To solve for m, we need to isolate it on one side of the inequality.

We can start by subtracting 4 from both sides:

28 - 4 > 1.5m

Simplifying:

24 > 1.5m

Next, we can divide both sides by 1.5:

16 > m

So Kate can travel at most 16 miles in the cab if she wants to spend no more than $28 on cab fare.

Therefore, the value of m in the inequality 28 > 4+1.5m is 16
