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

The constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4

For a graph with x and y-axis, we can say that y is directly proportional to "x" since it is a direct variation.

If y is directly proportional to x, this is expressed as:

y = kx

k is the required constant of variation.

Since the graph passes through the point (5,82), this shows that x = 5 and y = 82

Substituting into the formula:

82 = 5k

k = 82/5

k = 16.4

Hence the constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4

Answer:

y = -3x - 2

Step-by-step explanation:

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]

m = - 3

Therefore, equation of the line passing through (0, -2) and slope = -3 will be,

y + 2 = -3(x - 0)

y + 2 = -3x

y = -3x - 2

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

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:

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

Given :

Nami is wrapping packages with green and pink ribbon.

She has 11.85 meters of green ribbon and 13.4 of pink ribbon.

To Find :

How many more meters of pink ribbon are their than green.

Solution :

Length of green ribbon, g = 11.85 m .

Length of pink ribbon, p = 13.4 m .

Amount of pink more than green is :

A = 13.40 - 11.85

A = 1.55  m

Therefore, pink ribbon is 1.55 meter more than green one.

Hence, this is the required solution.
