Answer:

Step-by-step explanation:

Step one:

given data

the total amount of ounces= 97.5 ounces

we are told that the capacity of one bottle is 7.5 ounce

this means that they can actually fill up 97.5/7.5= 13 bottles

Step two:

We are told that one bottle was sold for $4.5

Hence they will sell 13 bottles for 13*4.5= $58.5

Answer:

$79.7468

Step-by-step explanation:

6.4% of 74.95 is 4.7968, since 6.4 * 74.95 is 479.68, and if you divide that by 100, you will get 4.7968. 4.7968 + 74.95 = $79.7468

Here we want to find the total cost of a coat given that we know its cost and the sales tax.

By working with percentages, we will find that the total cost will be $79.75

So the cost of the coat is $74.95, and then we must pay an extra 6.4%

Then we must pay a total of the 100% + 6.4% = 106.4%

And the 100% is equivalent to $74.95

Then the 106.4% is equivalent to:

(106.4%/100%)$74.95 = $79.75

So the total cost of the coat is $79.75

Answer:

The total cost of the games (play package)

= 15x - 5

Step-by-step explanation:

Number of tokens in the games = 15

The cost per token = x

Discount off the total cost = $5

Therefore, the cost of the play package = 15x - 5

where x is in dollars

However, ‘x’ can also assume any value.

Check:

If x = $15

The total cost of the game can be said to be 15(10) - 5 = $220

Answer:

The answer is at the bottom!!

Step-by-step explanation:

Another word for finding the opposite of an integer is negative number of an integer.

Decrease, spend, and decline are examples of words that mean negative. An integer is any positive whole number or its opposite. Here, opposite means sign. So a positive integer has a negative opposite and vice versa.

Answer:

[tex]\frac{73}{36}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]

1. Convert all the fractions to a common denominator.

For this problem, the common denominator will be 36

[tex]\frac{3}{4}[/tex] * 9 = [tex]\frac{27}{36}[/tex]

[tex]\frac{2}{9}[/tex] * 4 = [tex]\frac{8}{36}[/tex]

[tex]\frac{3}{2}[/tex] * 18 = [tex]\frac{54}{36}[/tex]

2. Substitute the values back into the equation, and solve

[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]

= [tex]\frac{27}{36}[/tex] - [tex]\frac{8}{36}[/tex] + [tex]\frac{54}{36}[/tex]

= [tex]\frac{19}{36}[/tex] + [tex]\frac{54}{36}[/tex]

Answer: Timothy will have $1,920 at the end of 4 years.

Step-by-step explanation: Remember, I=prt. So multiply 12,000x0.04x4. The final answer is $1,920.

Answer:

$1920

Step-by-step explanation:

He starts with 12,000 dollars. If he makes 4 percent of that, he is making 480 dollars every year. So you know how much he is making every year, you need to know what he is making in 4 years. 480 * 4 = 1920

Answer:

solve for x in the second equation is correct

Step-by-step explanation:

Here is the complete question

Which first step for solving the given system using substitution results in an equation without fractions?

(2x+6y=7

(6x + 18y = 24.... 2

Solve for x in the first equation,

Solve for y in the first equation,

Solve for x in the second equation

The best equation to she will be equation 2 since all the coefficients are end numbers

Let us make x t subject f the formula from equation 2;

From 2: 6x+18y = 24

Subtract 18y from both sides

6x+18y-18y = 24-18y

6x = 24-18y

Divide through by 6

6x/6 = 24/6 - 18y/6

x = 4-3y.

You can see that the resulting expression of x is not a fraction. Hence solve for x in the second equation is correct

We have to given that,

To plot the equation y = - 2x - 1 and the y-intercept on the graph.

Since, The equation of line in slope intercept form is,

y = mx + c

Where, m is slope and c in y - intercept.

Here, Equation is,

y = - 2x - 1

After comparing,

y - intercept = - 1

So, y - intercept of equation (0, - 1)

Step-by-step explanation:

Answer:

18.8 ft

20.8 ft

Step-by-step explanation:

Given that :

Dimension of rectangular patio:

13 feets * 15 feets

To double the area of The patio :

2 * initial. Area

Initial Area = area of rectangle = Length * width

Initial area = 13 * 15 = 195ft²

New area of patio = 2 * 195 ft² = 390 ft²

To obtain the new area, the length and width of patio increased in equal amount:

Let the Increment = x

Hence,

(length + x) * (width + x) = 390

(13 + x) * (15 + x) = 390

195 + 13x + 15x + x² = 390

195 + 13x + 15x + x² - 390 = 0

x² + 28x - 195 = 0

Using the quadratic equation solver to save computation time :

The roots are :

X = - 33.773 or 5.773

Dimension can't be negative, hence,

x = 5.773

New dimension :

(length + x) = 13 + 5.773 = 18.8 ft

(width + x) = 15 + 5.773 = 20.8 ft

Equation of a line passing through [tex](x_1,y_1)[/tex] and slope m is,

[tex]y-y_1=m(x-x_1)[/tex]

Slope of a line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through (0, -2) and (1, -5) will be,

Slope = [tex]\frac{-2+5}{0-1}[/tex]

Step-by-step explanation:

Given

[tex]Area = 5a^4 + 10a^3 - 15a^2[/tex]

[tex]Length = 5a^2[/tex]

Required

Determine the Width

The area of a rectangle is calculated using:

[tex]Area= Length * Width[/tex]

Make Width the subject

[tex]Width = \frac{Area}{Length}[/tex]

Substitute values for Area and Length

[tex]Width = \frac{5a^4 + 10a^3 - 15a^2}{5a^2}[/tex]

Factorize the numerator

[tex]Width = \frac{5a^2(a^2 + 2a - 3)}{5a^2}[/tex]

[tex]Width = a^2 + 2a - 3[/tex]

Hence, the polynomial for the width of the rectangle is:

[tex]Width = a^2 + 2a - 3[/tex]

Determine the number of 38 in 54

We start by representing the number of 38 in 54 with x

To determine the number of 38 in 54, we have to represented it as thus:

[tex]38 * x = 54[/tex]

Simplify the expression as follows:

[tex]38 x = 54[/tex]
