Answer:

The cost of one hot dog and the cost of one hamburger is $3.25

The cost of one hot dog is $1.75

Step-by-step explanation:

Let the number of hot dogs be represented by d and hamburgers be h

3d + 2h = 8.25 ----- eqn(I)

2d + 3h = 8.00 ----- eqn(II)

From eqn(I): d = (8.25 - 2h)/3

substitute the expression for d into eqn(II)

2d + 3h = 8

2(8.25 - 2h)/3 + 3h = 8

(16.50 - 4h) + 3h(3) = 8(3)

16.50 - 4h + 9h = 24

5h = 24 - 16.50

5h = 7.50

h = 7.50/5 = 1.50

One hamburger costs $1.50

d = (8.25 - 2h)/3 = (8.25 - 2×1.50)/3 = (8.25 - 3.00)/3 = 5.25/3 = 1.75

One hot dog costs $1.75

Cost of one hot dog and cost of one hamburger = $1.75 + $1.50 = $3.25

Answer:it is a location

Step-by-step explanation:

The others are simply wrong

The statement that can be said to be through about point is that a point is a location.

                   A point is a location in a geometry space used in demarcating an area or region with a dot representation. It does not have any long line or an endpoint. It does not also have a length or width. It is usually used to make a notion about a specified region.

For example:  If I want to measure a distance of 6 cm. I can place my divider from the mathematical set on the meter-rule and measure out 6 cm.

Then, place 6 cm on the plain sheet to show two different dots indicating the distance of 6cm before I draw the distance of 6cm with my drawing pencil.

Step-by-step explanation:

Your  F(x) = 2x - 4; GX) = 3x + 2; Hpx)=x2 requires a bit of guesswork for the reader to understand it.  I believe you meant:

F(x) = 2x - 4; G(X) = 3x + 2; H(x)=x2 Find FG H(2)

First find F(2):  f(2) = 2(2) - 4 = 0

Because this multiplicand is zero, further multiplication will result in zero also.  Thus, the final answer is zero (0).

Answer:

The answer in standard notation is 11'244,000. The answer in scientific notation is p * 10∧7, where p is 1.1244 and q is 7.

Step-by-step explanation:

Let's answer the question correctly this way:

Population of New York State = 19'650,000

Population of New York City = 8'406,000

Population that do not live in New York City = 19'650,000 - 8'406,000

Population that do not live in New York City = 11'244,000

Population that do not live in New York City in scientific notation = 1.1244 * 10⁷

The answer in standard notation is 11'244,000. The answer in scientific notation is p * 10∧7, where p is 1.1244 and q is 7.

Answer:

B. 16 sq. units

Step-by-step explanation:

If you divide the rectangle, you will get 2 triangles. Therefore you will divide your answer from the rectangle by two.

Step-by-step explanation:

here, on this as the measure of triangle is alredy given separately we don'tneed its area. We just can use formula of area of triangle and simpfy it to get answer.

the measures of perpendicular (p)= 8

and base (b)=4

now, area of triangle (a)=1/2×b×p

or, a = 1/2 ×4×8

by simplifying it we get 16 sq.units.

Answer:

  43.96 in^2

Step-by-step explanation:

The net shows the areas of the parts of the cone, so you simply need to add them up to get the total surface area.

  31.4 in^2 +12.56 in^2 = 43.96 in^2

Answer:

43.96 in.2.

Step-by-step explanation:

The surface area of a cone is the triangular shape and its circular base.

In this case, the top of the cone is 31.4 inches squared in area, and the circular base is 12.56 inches squared.

So, the surface area of the cone is 31.4 + 12.56 = 43.96 inches squared.

Answer:

A. The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

Step-by-step explanation:

Given

[tex]Equation\ 1: x - 3y = 1[/tex]

[tex]Equation\ 2: 7x + 2y = 7[/tex]

Required

Efficient way of solving the equations

The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;

The evidence is shown as follows;

Make x the subject of formula in equation 1

[tex]x = 1 + 3y[/tex]

Substitute 1 + 3y for x in equation 2

[tex]7x + 2y = 7[/tex]

[tex]7(1 + 3y) + 2y = 7[/tex]

Open bracket

[tex]7 + 21y + 2y = 7[/tex]

[tex]7 + 23y =7[/tex]

Make y the subject of formula

[tex]23y = 7 - 7[/tex]

[tex]23y = 0[/tex]

Divide both sides by 23

[tex]\frac{23y}{23} = \frac{0}{23}[/tex]

[tex]y = 0[/tex]

Recall that x = 1 + 3y

Substitute 0 for y in the above expression

[tex]x = 1 + 3(0)[/tex]

[tex]x = 1 + 0[/tex]

[tex]x = 1[/tex]

Solving for y in the second equation will take more steps

Answer:

A: The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

Answer:r

Step-by-step explanation:

On isolating 'a', from the given equation M = 7a + 5ab, we get the value of a = M/(7 + 5b). Hence, option B is the right choice.

The isolation of a variable is a process to take one variable on one side of the equation and everything else on the other side. This is done following a set of mathematical operations.

In the question, we are asked to solve for a, from the given equation:

M = 7a + 5ab.

To solve for a, we will isolate 'a' on one side of the equation, and on the other side, we will have the value of 'a'.

To isolate 'a', we will follow these steps:

M = 7a + 5ab

or, M = a(7 + 5b) ... (Taking a common between 7a and 5ab)

or, a(7 + 5b) = M ... (Changing the sides)

or, {a(7 + 5b)}/(7 + 5b) = M/(7 + 5b) ... (Dividing both sides by (7 + 5b))

or, a = M/(7 + 5b) ... (Simplifying)

Thus, on isolating 'a', from the given equation M = 7a + 5ab, we get the value of a = M/(7 + 5b). Hence, option B is the right choice.

Explanation:

Let's label the corner points of the triangle A,B,C starting at the origin and moving clockwise

A = (0,0)

B = (2,-4)

C = (-4,-4)

Dilating with a scale factor 2 means we multiply each coordinate of each point by the value 2

A = (0,0) becomes A' = (0,0). No change happens. This point is fixed

B = (2,-4) becomes B' = (4,-8). This point does move

C = (-4,-4) becomes C' = (-8,-8). This moves as well

So all you need to do from here is draw triangle A'B'C'.

-----------------

Side note: the lengths of triangle A'B'C' are twice as long as their counterparts on triangle ABC. Consequently, this means the perimeter of A'B'C' is twice as long as the perimeter of ABC. Also, triangle A'B'C's area is four times larger than the area of triangle ABC.

HOPE THIS HELPS!!! :)

PLEASE LET ME KNOW IF IM WRONG!!!

Step 2, is the subtraction property of equality, Option A is correct.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here, while reviewing the steps,
In step 2, there is an elimination of 7, by adding 7 on both side because both sides consist of  -7,
When +7 add to both side, it becomes,
-7 + 7 rearranging gives, 7 - 7 = 0

Thus, Step 2, is the subtraction property of equality, Option A is correct.
