3 less than 8 times w

Answer:

This has infinite solutions.

Step-by-step explanation:

Key skills needed are: One variable equations, Algebra, Adding/Subtracting Like Terms

1) We first start with the equation: 8 + 2 (x - 6 ) = -2 +2x - 2​

2) We first need to use distribution property for the parentheses.

We need to distribute the 2 to the x and the -6.

3) This would be 8 + 2x - 12 = -2 +2x - 2

4) The next thing to do is combine like terms.

Like terms are terms with the same variable, or no variable at all. 8 and 6 would be like terms, and 2x and 4x would be like terms. 2x^2 and 4x would not be like terms as one has x^2 and the other has only x.

3) Now you know what like terms are, you can implement this into the problem --> Combine the 8 and 12 on the left side  + Combine the -2 and -2 on the right side ----> 2x-4 = 2x-4

4) Since both sides have the same exact thing (both sides have 2x-4) this equation has infinite solutions.

Hope you understood and have a nice day!! :D

Step-by-step explanation:

Negative slope

Its going from left to right.

Answer:

1=(4/4)*(4/4)

2=(4/4)+(4/4)

3 = (4+4+4)/4

4 = 4 + (4-4)*4

20=4 × (4/4 + 4)

20=4 × (4/4 - (-4))

[tex]20 = \sqrt{4} +\sqrt{4} + (4x4)[/tex]

[tex]20 = \sqrt{4} +\sqrt{4} + (-4 x -4)[/tex]

Answer: The answer is A, $78.00

Step-by-step explanation: Hope it helps

The required cost of the item after 4% of sales tax is given as $78.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Let the total cost of the item be x,
According to the question,
x = cost + sales tax
X = 75 + 4% of 75
x = 75 + 3
x = $78

Thus, the required cost of the item after 4% of sales tax is given as $78.

Step-by-step explanation:

Base of smaller pink triangle

= (3m + 6m) - 7m = 2m.

Area of smaller pink triangle

= 0.5(2m)(5m) = 5m².

Area of bigger pink triangle

= 0.5(6m)(5m) = 15m².

Hence total area shaded = 5m² + 15m² = 20m².

Answer:

Is there a picture for this one and also you didn't mention the slope of the red line is?

Step-by-step explanation:

Answer:

The slope of the Green line should be the same as the red line- but a negative number instead of a positive.

Step-by-step explanation:

This is the inverse of the line

So by reflecting it over the y-axis, the slope remains the same but will change from positive to negative and vise versa

Ayooo why u eating a glizzy ;-;

Step-by-step explanation:

Answer:

-11

8 = 2x + 30

8 - 30 = -22

-22 ÷ 2 = -11

x = -11

Also if you place 2×(-11) + 30 you get 8

Answer: 30 + 10.50h

Step-by-step explanation:

From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.

The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:

= $30 + $10.50h

where h represents the number of hours for tutoring used.

For example, if 2 hours if tutoring was used, the total amount earned would be:

= 30 + 10.50h

= 30 + 10.50(2)

= 30 + 21

= $51

Answer:

1) 9

2)5.85

Step-by-step explanation:

Answer:

Step-by-step explanation:

Mark gave 1.80 tip which was 20% of the meal

1.80...................20%

? ........................100%

the meal was 9 dollars ,  1.80*5=9

second problem

finance charge was 15% which amounts 39.00 dollars

if 15% is 39 dollars

5% is 39/3=13

100% is 13*20=260

260 was the original price

Answer:

x+4+2x = 20+5x-32

Step-by-step explanation:

x+4+2x

= 3x + 4

20+5x-32

= 20-32+5x

= 5x-12

Finding the value of X

3x+4 = 5x-12

= 4+12 = 5x-3x

= 16 = 2x

= 16/2 = X

= 8 = X

By putting the value of X in the equation

(3×8)+4

= 24 +4

= 28

(5×8)-12

= 40-12

28

28 = 28

so the X+4+2x < 20+5x-32 is wrong

Answer:

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

Step-by-step explanation:

16 - 12x = 4y

Add -16 to both sides.

-12x + 16 + (-16) = 4y + (-16)

-12x = 4y - 16

Then divide both sides by -12

-12x / (-12) = [tex]\frac{4y-16}{-12}[/tex]

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

Answer:

They are similar.

Step-by-step explanation:

They are similar because, the top triangle has one more square to the height as well as the width. If you take one square away from the height and width the top triangle is the same size as the bottom triangle.

A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25 meters thick. Let y represent the ice sheet's thickness ( in meters) after x weeks. Complete the equation for the relationship between the thickness and number of weeks.

Answer:

y = 2 - 0.25x

Step-by-step explanation:

From the question, the initial thickness of the ice sheet = 2 meters,

After 3 weeks, the thickness of ice sheet reduced to 1.25 meters

Hence, the difference in the thickness in 3 weeks is calculated as:

2m - 1.25m = 0.75m

The amount of changes that occurred in 3 weeks is given as:

= 0.75/3 = 0.25 meters,

We are told that, the ice is melting with the constant rate.

Therefore, the equation for the relationship between the thickness and number of weeks is given as:

y = 2 - 0.25x

Answer: the answer above is correct
