Help pls. Three sodas cost$4.50 at a convenience store. How many would it cost to buy 10 sodas at the same price.

Answer:

b1= 2A/h - b2

Step-by-step explanation:

You have to multiply each side by 2, then divide each side by h. after that you subtract b1 from both sides and then you will get your answer.

Answer:

b1 = 2A / h - b2

Step-by-step explanation:

A = h(b1 + b2) / 2

[cross multiply]

h(b1 + b2) = A × 2

b1h + b2h = 2A

[divide both sides of the equation by h]

b1h / h + b2h / h = 2A / h

b1 + b2 = 2A / h

[make b1 the subject of the formula]

b1 = 2A / h - b2

a=127

Answer:

Student tickets: 287

Adult tickets: 134

Step-by-step explanation:

Students: x

Adults: y

a) x + y = 421

b) 2x + 5y = 1,244

a) x = 421 - y

b) 2 (421 - y) + 5y = 1,244 (substitution)

842 - 2y + 5y = 1244

3y = 1244 - 842

y = 402/3

y = 134 adult tickets

421 - 134 = 287 student tickets

Answer:

A candy bar costs $0.80

A bag of chips costs $6.20

Step-by-step explanation:

Let's call candy bars x, and bags of chips y.

Ruben ought 2x and 4y for $24

Lucis bought 2x and 2y for $14

This means that 2x+4y = 24 and 2x+2y = 14

Now we have a system of equations that we can solve.

2x + 2y = 14

2(x + y) = 14

x + y = 7

y = 7 - x

Plug this into the next equation to get:

2x + 4y = 24

2x + 4(7 - x) = 24

2x + 28 - 7x = 24

28 - 5x = 24

-5x = -4

x = -4/-5

x = 4/5 = 0.8

plug that x value into y = 7 - x to find y

y = 7 - x

y = 7 - (4/5)

y = 245/35 - 28/35

y = 217/35 = 6.2

now we can check our work:

2(x + y) = 14

2(6.2 + 0.8) = 14

2(7) = 14

14 = 14

^ this means our values are correct

Answer:

A candy bar costs $0.80

A bag of chips costs $6.20

Step-by-step explanation:

1. y--7=-2(x-0)

y+7=-2x

y=-2x-7

2. y--3=-2(x-1)

y+3=-2x+2

y=-2x+2-3

y=-2x-1

Answer: 360

Step-by-step explanation:

If you double 18 and then multiply by 10 will be 360.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ 18 x 20

The product of the numbers 18 and 20 will be 360.

If you double 18 and multiply the number by 10 will be

2(18) x 10 = 36 x 10 = 360

If you double 18 and then multiply by 10 will be 360.

Answer:

Step-by-step explanation:

We will first have to find the fraction of the whole land goats use. If we add 2/5 and 1/4, we will get 13/20. Simplifying the expression 1-13/20 gets 7/20, which is the total fraction of land the goat and sheep has. The goat will then get 7/20*1/7 of the whole land, which is 1/20. The sheep will then get 7/20*6/7 of the entire land, which is 3/10. Because 1/20 of the whole land is 12 acres, the farmer has 240 acres. SImplifying the expression 240*3/10 gets 72 acres

Let the height of rectangle be = x,

Area of rectangle = base × height

so, there are two cases now,

Case - 1 :

here, value of x (length) is negative, measure of length can't be negative, so length is not equal to -4/3

Case - 2 :

here, value of x = 4, and satisfys the condition so

The rectangle's height is 4 inches and the rectangle's base is also 4 inches.

Let's assume the height of the rectangle is 'h' inches.

According to the given information, the base of the rectangle is 8 inches shorter than three times its height. This can be expressed as:

Base = 3h - 8

The area of a rectangle is given by the formula:

Area = Length * Width

In this case, the area is given as 16 square inches. We can set up the following equation:

16 = h * (3h - 8)

Expanding the equation:

[tex]16 = 3h^2 - 8h[/tex]

Setting the equation equal to zero:

[tex]3h^2 - 8h - 16 = 0[/tex]

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's solve it using the quadratic formula:

[tex]h = (-b \± \sqrt{b^2 - 4ac}) / (2a)[/tex]

For this equation, a = 3, b = -8, and c = -16. Plugging in the values:

[tex]h = (-(-8) \± \sqrt{(-8)^2 - 4 * 3 * (-16)}) / (2 * 3)\\\\h = (8 \± \sqrt{64 + 192}) / 6\\\\h = (8 \± \sqrt{256}) / 6\\\\h = (8 \± 16) / 6[/tex]

We have two possible values for h:

h₁ = (8 + 16) / 6 = 4

h₂ = (8 - 16) / 6 = -1

Since the height of a rectangle cannot be negative, we can discard the value h₂ = -1.

Therefore, the rectangle's height is 4 inches.

Now, we can find the base of the rectangle:

Base = 3h - 8

Base = 3 * 4 - 8

Base = 12 - 8

Base = 4

Therefore, the rectangle's base is also 4 inches.

The Correct choice is :

D. Both ll and lll

Answer:  36°  and 54°

Step-by-step explanation:

Let the larger angle be 'R' and the smaller angle 'q'

⇒       R + q = 90     [since complementary angles have a sum of 90°]

Then  R - q = 18   [since 1 of 2 complementary angles is 18 less than other]

We can combine the equation

(18 + q) + q = 90

     18 + 2q = 90

            2q = 72

               q = 36

We can solve for R

             R - 36 = 18

                    q = 36 + 18

                    q = 54

The statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.

We have some statements that describes how ultrasound can produce an image.

The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body to provide the information necessary to produce an image.

Therefore, the statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

Step-by-step explanation:

In the given equation, y = 1/3x, where it represents a proportional relationship:

1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.

The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.
