Answer:

x>-3

Step-by-step explanation:

3x+12>3

3x>-9

x>-3

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

Step-by-step explanation:

Answer:

63

Step-by-step explanation:

Ty worked 4 hours ad earned $28. This means that he earned $7 per hour. So, 7 times 9 is equal to 63. Which means that Ty will earns $63 in 9 hours.

Answer:

$27.60

Step-by-step explanation:

First, we need to find how much the tip is:

we can convert 15% directly to a decimal:

15% = 0.15  

Then we find :

15% of 24 = 0.15 x 24 = 3.59999999999999

3.599999999999999 to the nearest cent is 3.60

Then we add the tip to the original bill:

3.60 + 24 = 27.60

So the total cost of the lunch is $27.60

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

Answer:

50 : 25 = 75 : 37.50

Step-by-step explanation:

If 50 apples cost $25, that means 2 apples cost $1.

75 apples cost 37.5, or $37.50

Answer:

97 words in 1 minute

Step-by-step explanation:

A unit measure is so many somethings done usually per unit time. Examples

3 crackers and 1 apple is not. For ever apple, she ate 3 crackers would be

1 cookie is not. It is not per anything.

Driving 16 miles is not. Again, it is not per anything.

The answer is 97 words in 1 minute.

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=(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]

Step-by-step explanation:

The x is a multiplication sign not a variable, I hope this right.  Good luck, I am so tired.

Ayooo why u eating a glizzy ;-;

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

First your going to need to find 6% of 450 which is 27

then you need to find 6% of 250 which is 15 and you have two 250's so you have two 15's

next add them all up and you got yourself 57

btw sorry my explanation sucks

Answer:

57$

Step-by-step explanation:

450 + 500 = 950 and 6% of 950 is 57

Answer: 0.51

Step-by-step explanation:

We know that:

For a random selection, we have a probability of 0.42 where the house has both services and a probability of 0.82 that the house has only internet service.

Let's suppose that the percentage of houses the houses with internet service (the 82% of the total) that also have a home phone is X

Then we must have that, (X/100%) times the 0.82, must be equal to 0.42

(X/100%)*0.82 = 0.42

X = (0.42/0.82)*100% = 51%

This means that 51% of the houses with internet service, also have a home phone.

Then the probability that a house has a home phone given that it has internet service, is equal to:

51%/100% = 0.51

The probability is 0.51

Answer:

If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.

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.

Answer:

Harper is 200 yards away from her home if the map shows 3 inches

Step-by-step explanation:

50 yards = 3/4 inch

3 inches = 3/1

3/1 x 4/4 = 12/4

12/4 = 3 inches

50 x 4 = 200

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.

#SPJ6

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

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.
