Abigail buys 12 bottles of grapefruit juice at the corner store for a total cost of $12.48. If each bottle costs the same amount, how much is 19 bottles of juice?

the given expression is,

16x = 156.8

x = 156.8/16

x = 9.8

thus, the answer is 9.8

Answer:

x = 9.8

Step-by-step explanation:

16x=156.8

x = 156.8/16

x = 9.8

Answer: $1.33

This can be worked out as a simple algebra problem: 15x=20, x being 1 pizza dough. In order to find the value of one pizza dough (x) you need to isolate it. To do that, divide 15 from both sides and you'll be left with x=1.33

15x=20

/15   /15

x=1.33

The equation of the line that passes through the point (-4, -5) and is parallel to y = 1/2x -4 is y = 1/2x - 3

From the question, we are to determine the equation of the line that passes through the given point and is parallel to the given equation.

The given point is (-4, -5)

The given equation is y = 1/2x - 4

NOTE: If two lines are parallel, then their slopes are equal

Now, we will determine the slope of the given line '

y = 1/2x - 4

Compare to the general form of an equation of a straight line

y = mx + b

Where m is the slope

and b is the y-intercept

Therefore, m = 1/2

That is, the slope of the line is 1/2

Now, we will determine the equation of the line that has a slope of 1/2 and that passes through the point (-4, -5)

Using the point-slope form of the equation of a straight line

y - y₁ = m(x - x₁)

Then,

y - (-5) = 1/2(x - (-4))

y + 5 = 1/2(x + 4)

y + 5 = 1/2x + 2

y = 1/2x + 2 - 5

y = 1/2x -3

Hence, the equation of the line is y = 1/2x - 3

Option A

The other expression for this scenario is 5.25 + 5.25 + 5.25 + 5.25

From the question, we have the following parameters that can be used in our computation:

Cost of cotton candy = $5.25

Number of friends = 4

So, the expression is given as

Expression = 5.25(4)

Express 4 as 1 + 1 + 1 + 1

So, we have the following representation

Expression = 5.25(1 + 1 + 1 + 1)

Open the bracket

Expression = 5.25 + 5.25 + 5.25 + 5.25

Hence, the other expression is 5.25 + 5.25 + 5.25 + 5.25

The excise tax on 1 gallon of gasoline = 18.2 cents

You will buy 18.5 gallons

We need to find the excise tax you should pay

At first let us change the cent to dollar

1 cent = 1/100 dollars

18.2 cents = 18.2 * 1/100 = 0.182 dollars

Now you will buy 18.5 gallons

You will pay = 18.5 * 0.182 = 3.367 Dollars

The state excise tax = $3.367

Round the number to the nearest cent, then it will be $3.37

The number of ways the customer can select 4 appetizers , 4 main course and 4 desserts for a banquet is 220500 ways .

In the question,

it is given that ,

number of appetizers that catering service can offer = 6

number of main courses that catering service can offer = 8

number of desserts that catering service can offer = 4 ,

The number of ways 4 appetizers can be selected out of 6 = ⁶C₄

number of ways 4 main courses can be selected out of 8 = ⁸C₄

number of ways 4 desserts can be selected out of 10 = ¹⁰C₄

So , total number of ways = ⁶C₄ × ⁸C₄ × ¹⁰C₄

= 15 × 70 × 210

= 1050 × 210

= 220500 ways

Therefore , The number of ways the customer can select 4 appetizers , 4 main course and 4 desserts for a banquet is 220500 ways .

-6 = 3x - 6y

4x = 4 + 5y

ok

x = (4 + 5y)/4

Substitution

The expression to represent the change in elevation would be 13 - 150.

The change in elevation would be - 137 feet.

The change in elevation refers to the difference between the elevation that a person ends up in, from the elevation that they started out at.

The change in elevation for the goat would therefore be:

= Ending elevation - Starting elevation

= 13 - 150

= - 137 feet

In conclusion, the change in elevation of the goat in its travels was - 137 feet.

Answers:

We see that ∠2 and ∠3 are corresponding angles

And since the lines u and v are parallel, ∠2 and ∠3 are congruent.

So, m∠3 = 150

We see that ∠1 and ∠2 are vertically opposite angles

Thus, ∠1 and ∠2 are congruent

So, m∠1 = 150

The relationship between ∠1 and ∠3 is an example of the following rule

When parallel lines are cut by a transversal, alternate interior angles are congruent.

Explanation:

The angles formed by two parallel lines and a transversal that are on the same side of the transversal and in the same position from the parallel lines are called corresponding angles. These angles have the same measure so they are also congruent.

So, we can fill the first part as:

We see that ∠2 and ∠3 are corresponding angles

And since the lines u and v are parallel, ∠2 and ∠3 are congruent.

So, m∠3 = 150

On the other hand, two opposite angles formed by two lines that cross are called vertically opposite. So, these angles have the same measure.

So, we can fill the second part as:

We see that ∠1 and ∠2 are vertically opposite angles

Thus, ∠1 and ∠2 are congruent

So, m∠1 = 150

Finally, we can fill the third part as:

The relationship between ∠1 and ∠3 is an example of the following rule

When parallel lines are cut by a transversal, alternate interior angles are congruent.

Because alternate interior angles are the angles that are inside the parallel line and on opposite sides of the transversal.

Answer:

length = 12 miles

width = 6 miles

Step-by-step explanation:

        length = x miles

       width = (x - 6) miles

  Area of rectangle = 72 square miles

         length * width = 72

           x * (x - 6)        = 72

          x*x - 6*x          = 72

             x² - 6x - 72 = 0

Sum = -6

Product = -72

Factors = 6 , (-12)         { 6 + (-12) = -6 and 6*(-12) =-72 }

Rewrite the middle term using the factors.

x² + 6x - 12x - 72 = 0

x(x + 6) -12(x + 6) =0

(x + 6)(x - 12) = 0

    {x + 6 = 0 is rejected as length will not have negative value}

x - 12 = 0

     [tex]\sf \boxed{\bf x = 12 \ miles}[/tex]

length = 12 miles

Width = 12 - 6 = 6 miles

The function describes the motorboat's distance from the shore

y = -4x+50

Given,

In the question:

A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore

After 9 minutes, it is 14 km from the shore.

So, The rate of change =

                 =   [tex]\frac{Final Distance - initial distance}{time} \\\\\frac{14-50}{9} = -4[/tex]

Negative sign shows that there is decrease in distance per minute

The rate of change of distance is 4 km / minutes

General equation : y = mx+ c

Where m is the slope and c is the constant

Substitute the values in the equation :

y= -4x +50

Where y is the final distance and x is the minutes
