have an amazing day! (❁´◡`❁)

Step-by-step explanation:

The word equation for "eight more than the number of children is 24" can be written as:

Number of children + 8 = 24

Let's break it down step by step:

1. Identify the unknown: The unknown in this equation is the number of children. Let's represent it as "x".

2. Translate "eight more than the number of children" into mathematical language: "Eight more than" means adding 8 to the number of children.

3. Write the equation: The equation becomes x + 8 = 24.

To find the value of x, we need to isolate it on one side of the equation. We can do this by subtracting 8 from both sides:

x + 8 - 8 = 24 - 8

Simplifying further:

x = 16

Therefore, the number of children is 16.

It's important to note that the word equation can be translated into different mathematical expressions. For example, another way to represent "eight more than the number of children is 24" would be:

Number of children = 24 - 8

This equation would also yield the same answer: 16.

Remember, word equations help us represent real-life situations in mathematical form, allowing us to solve problems and find solutions.

Step-by-step explanation:

Given

2x + 10 = 6 ( divide all 3 terms by 2 )

x + 5 = 3 ← equivalent equation

The equation which is equivalent to 2x + 10 = 6 from the given options is x + 5 = 3.

Given the equation in the question:

2x + 10 = 6

Options:

A) 2x = 4

B) x + 5 = 3

C) x + 10 = 3

D) 2x + 6 = 10

To find the equation that is equivalent to 2x + 10 = 6, we check each of the options.

For A) 2x = 4

2x + 10 = 6

2x = 6 - 10

2x = -4

Option A is wrong.

For B) x + 5 = 3

2x + 10 = 6

Divide each term by 2:

2x/2 + 10/2 = 6/2

x + 5 = 3

Option B is correct.

For C) x + 10 = 3

2x + 10 = 6

Divide each term by 2:

2x/2 + 10/2 = 6/2

x + 5 = 3

Option C is wrong.

For D) 2x + 6 = 10

2x + 10 = 6

Subtract 6 and 10 from both sides:

2x + 10 - 10 - 6 = 6 - 6 - 10

2x - 6 = -10

Option D is wrong.

Therefore, x + 5 = 3 is equivalent  to the equation.

Option B) x + 5 = 3 is the correct answer.

Therefore the price of an foundation drink is $ 3.20(approx).

Step-by-step explanation:

Let the price of one fountain drink be x and one beg of popcorn be y.

The Clayton family bought 4 fountain drinks and 3 begs of popcorn and paid $22.50. The Hanks family bought 5 fountain drinks and 2 begs of popcorn and paid $23.75.

According to the problem,

4x+3y=22.50..............(1)

5x+2y=23.75..............(2)

Equation (1)×5 - Equation (2)×4

20x+15y-(20x+8y)=112.5-91

⇔20x + 15y -20 x-8y=21.5

y+10=4x-12

y=4x-12-10

y=4x-22

Answer:

The correct answer is: [tex]4\frac{3}{5}[/tex]

Step-by-step explanation:

According to the rule of BODMAS, division is done before addition.

So, in a + b ÷ c, we will first calculate,  b ÷ c

Given b =  [tex]2\frac{2}{5}[/tex] = [tex]\frac{12}{5}[/tex] , c = [tex]\frac{3}{4}[/tex] .

So, [tex]\frac{b}{c}[/tex] = [tex]\frac{12}{5}[/tex] ÷ [tex]\frac{3}{4}[/tex]

So, [tex]\frac{b}{c} = \frac{12}{5} \times\frac{4}{3}[/tex] , as the numerator and denominator gets reversed as division is changed to multiplication.

So, [tex]\frac{b}{c} = \frac{16}{5}[/tex] .

Next the value of a to  [tex]\frac{b}{c}[/tex]  , where, [tex]a = 1\frac{2}{5} = \frac{7}{5}[/tex], we get,

[tex]\frac{7}{5} +\frac{16}{5} = \frac{23}{5} = 4\frac{3}{5}[/tex].

Answer:

Step-by-step explanation:

Divide 40 by 4, and you get 10. 10 rows.

Cost of item of $ 310 including the sales tax is $358.05.

Convert the percentage rate of sales tax to a decimal by dividing the percentage by 100.

A 15.50% sales tax rate becomes 0.155 when converted to a decimal.

After performing the multiplication, you will get the amount of sales tax that needs to be added to the item's price. So, $310  x 0.155 = $48.05.

Therefore, the total cost of the item after sales tax would be the original price plus the amount of sales tax, which is $310 + $48.05 = $358.05.

2) Option 9.4 is correct

Therefore the length of the given line segment is [tex]s=9.4[/tex] units

3) Option (1,1) is correct

Therefore the midpoint of the given line  segment is M=(1,1)

Step-by-step explanation:

2) Given that the line segment CD with endpoints C at (-3,1) and endpoint at D (5,6)

To find the length of the given line segment :

That is to find the distance of the end points using distance formula

[tex]s=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] units

Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-3,1) and (5,6) respectively

Substitute the points in the distance formula we have

[tex]s=\sqrt{(5-(-3))^2+(6-1)^2}[/tex] units

[tex]=\sqrt{(5+3)^2+(5)^2}[/tex] units

[tex]=\sqrt{8^2+5^2}[/tex]

[tex]=\sqrt{64+25}[/tex]

[tex]=\sqrt{89}[/tex]

[tex]=9.4[/tex]

Therefore [tex]s=9.4[/tex] units

Option 9.4 is correct

Therefore the length of the given line segment is [tex]s=9.4[/tex] units

3) Given that the line segment PG with point P at (-6,4) and point at G (8,-2)

To find the midpoint of the given line segment :

Midpoint formula is [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-6,4) and  (8,-2) respectively

Substituting the points in the midpoint formula we get

[tex]M=(\frac{-6+8}{2},\frac{4-2}{2})[/tex]

[tex]=(\frac{2}{2}+\frac{2}{2})[/tex]

[tex]=(1,1)[/tex]

Therefore M=(1,1)

Therefore option (1,1) is correct

Therefore the midpoint of the given line  segment is (1,1)

Answer:

The answer is b. $ 74.75

Step-by-step explanation:

Data:

Let x be the value of items to be insured.

1. if the items are more than $ 3 000 it means that x is greater than  $  3000 and the annual premium will be 23 % of the total value.

2. if the items are less or equal to  $ 3 000, it means that x ≤ $ 3 000 ( in other words, x is less than or equal to $ 3 000)

The annual premium for the goods will be:

annual premium = 23 % × $ 3900

                          = $ 897

However, the premium is supposed to be paid monthly. Divide the total premium by 12 to get:

$ 897/12 = $ 74.75

Answer:

4.2

Step-by-step explanation:

5.7-1.5=4.2

Answer: x = 4.2

Explanation: If we're asked to solve for x in the equation x + 1.5 = 7.5, what we're really being asked to do is get x by itself on one side of the equation.

So if we take a look at the left side of our equation, notice that 1.5 is being added to x so in order to get x by itself, we must subtract 1.5 from the left side of the equation. Now remember your first rule of solving equations. If we subtract 1.5 from the left side of the equation, we must also subtract 1.5 from the right side of the equation.

So on the left side our +1.5 and -1.5 cancel out and we're simply left with x. On the right side of the equation,

5.7 - 1.5 simplifies to 4.2 so our answer is x = 4.2.

The nice thing about solving equations is that you can always check your answer by plugging it back in to the original equation.

So here, we're gonna plug a 4.2 back in for x in the original equation and we get (4.2) + 1.5 = 5.7.

Since 4.2 + 1.5 = 5.7 is a true statement, our answer checks and we know that it's right.
