The value of x in the isosceles triangle is 9.25.

An isosceles triangle is a polygon that has three sides. The opposite length have the same length and equal angles.  has two opposite sides. If the two angles are equal , it means the triangle is an isosceles.

Th perimeter of an isosceles triangle is the sum of the length of the three sides of the triangle.

Perimeter = (2 x length of leg) + base

43 = (2x x) + 2x - 6

43 = 2x + 2x - 6

43 = 4x - 6

43 - 6 = 4x

37 = 4x

x = 37 / 4

The given expression 7x - y = -9 in the slope intercept form can be represented as y = 7x + 9.

The expression given to us is -

7x - y = -9

We have to represent this in the slope intercept form.

The slope intercept form can be represented as -

y = mx + c

where, y = y coordinate of the line

           m = slope of the line

            x = x coordinate of the line

            c = y intercept of the line

Thus, representing the given expression in the slope intercept form, we have

7x - y = -9

=> -y = -7x - 9

=> y = 7x + 9

Thus, the given expression in the slope intercept form can be represented as y = 7x + 9.

The answer of the given question is $6.4, this is the money that need to be added onto the bill for the tip.

How to calculate a 20% tip?

To calculate tip, we need to multiply the total bill by 1 plus the decimal percentage tip we'd like to leave. If we wanted to leave a 20% tip, we would add 1 to 0.20 to get 1.20. Then, multiply the bill by 1.20 to get the total amount we'd leave including tip.

In this case, we have a $32 bill and we would like to add on an 20% tip. So, it will be as follows:

20% = 0.20

1 + 0.20 = 1.20

Total bill will be 1.20 x $32 = $38.4

Hence, the tip amount is $38.4 - $32 = $6.4

The inequality represents the situation group of parents who would like to earn at least $600, after paying for the cost of renting the space $40 an hour, and charging $8 per person for entry into the event is 8x - 4y ≥ 600, and x > 0, Y > 0.

We are given the following;

They charge $8 per person for entry into the event.

The group would like to earn at least $600, after paying for the cost of renting the space, which is $40 an hour.

Let the number of people be x and the number of hours they are present in the space be y.

Per person entry cost is $8.

Donations by all the people entering the space are 8x.

The per hour cost of rent is $40.

The total cost of renting the space is 40y which will be subtracted from the total amount of donations.

They plan to earn a minimum of $600.

So, the inequality will be given by;

8x - 4y ≥ 600 and x > 0, Y > 0.

Thus, the inequality represents the situation group of parents who would like to earn at least $600, after paying for the cost of renting the space $40 an hour, and charging $8 per person for entry into the event is 8x - 4y ≥ 600, and x > 0, Y > 0.

The equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

y + 3 = -12/7(x - 5)

Given, a line that passes through the points (5, −3) and (−2, 9).

Now, we have to find the equation of the line in point-slope form.

As, we know to find the equation of a line,

(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)

Now, using the above formula, we get

(y + 3)/(x - 5) = (-3 - 9)/(5 + 2)

(y + 3)/(x - 5) = -12/7

On cross-multiplying, we get

y + 3 = -12/7(x - 5)

Hence, the equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

y + 3 = -12/7(x - 5)

Step-by-step explanation:

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of AgCl when treated with excess ag⁺  is 17.2%

The percent of chloride can be calculate as follow:

Mass of AgCl precipitated = 1.750 g

Molar mass of AgCl = 143.32 g/mol

Molar mass of Chlorine atom = 35.45 g/mol

Asume, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.

To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:

In 143.32 g of silver chloride, mass of chlorine present is 35.45 g

So, in 1.3487 g of silver chloride, mass of chlorine present will be =

35.45g/143.32 g * 1.750 g = 0.43 g

To calculate the percentage composition of chlorine in pure chloride compound, as follows:

Mass of pure chloride compound = 2.500 g

Mass of chlorine = 0.43 g

% Chlorine = 0.43/2.5 *100

% Chlorine = 17.2 %

Therefore, the mass percentage of chloride in pure chloride compound is 17.2%

13x-12y+6xy

Step-by-step explanation:

To  make this easier, we can rearrange these terms, and get

5x+8x-12y+2xy+4xy.

x and y just represent variables, so we can combine 5x and 8x to get 13x, and we can combine 2xy and 4xy to get 6xy.

Now we have 13x-12y+6xy, and nothing else can be combined.

Answer:

x = 8

Step-by-step explanation:

since the triangle is isosceles then the 2 legs are congruent, that is both 4x - 3

the perimeter is the sum of the 3 sides , that is

x + 4x - 3 + 4x - 3 = 66

9x - 6 = 66 ( add 6 to both sides )

9x = 72 ( divide both sides by 9 )

x = 8

The amount of pure antifreeze that needs to be added = 1.429 quarts

What is antifreeze ?

A colored liquid called antifreeze, often known as engine coolant, is combined with water to assist regulate your engine in extremely hot weather.

Let x be the amount of pure antifreeze that needs to be added

The amount of pure antifreeze added (x) plus the amount of pure antifreeze in the 5 quart of 10% antifreeze solution [ 0.1*5] should be equal to the amount of pure antifreeze in the final mixture [ 0.3*(5+x) ]

The equation obtained is:

x+[0.10*5]=0.30(5+x)

x+0.5=1.5+0.30x

x-0.30x =1.5-0.5 = 1

0.70x=1

divide each side by 0.70

x=1.429 quarts

So, the amount of pure antifreeze that needs to be added = 1.429 quarts
