At a restaurant, Hamburgers cost $2.50 each and French Fries cost $1.20 each. If I went to this restaurant, and bought $8.60 worth of food,

write an equation which models how many hamburgers and french fries I purchased.

Let H represent Hamburgers

Let F represent French Fries.

**Answer:**

2.50h+1.20f=8.60

**Step-by-step explanation:**

Since the total cost of food costs $8.60, add together the costs of however many burgers and however many fries you bought. 2.50 and 1.20 are multiplied by the amount of food you purchase

2334567Happy Paws charges $19.00 plus $2.50 per hour to keep a dog during the day. Woof Watchers charges$10.00 plus 53.75 per hour. Complete the equation and solve it to find for how many hours the total costof the services is equal. Use the variable h to represent the number of hours.The equation isThe total cost of the services will be equal athours.

Let h be the hours and y the total charge. Then, for Happy Paws, we have

[tex]y=2.50h+19[/tex]and for Woof Watches, we have

[tex]y=3.75h+10[/tex]Then, we need to solve these equations.

Solving by elimination method.

If we multiply by -1 the first equation, we have the equivalent system of equations:

[tex]\begin{gathered} -y=-2.50h-19 \\ y=3.75h+10 \end{gathered}[/tex]If we add both equations, we obtain

[tex]0=(3.75-2.50)h+10-19[/tex]because y-y=0. Then, it yields,

[tex]0=1.25h-9[/tex]If we move -9 to the left hand side as -9, we have

[tex]\begin{gathered} 9=1.25h \\ h=\frac{9}{1.25} \\ h=7.2 \end{gathered}[/tex]Hence, to find the total cost, we must substitute this values into one of the 2 equations. If we choose the first one, we obtain

[tex]\begin{gathered} y=2.50(7.2)+19 \\ y=18+19 \\ y=37 \end{gathered}[/tex]**Then, the answers are:**

**The equation is**

**and, the total cost of the services will be equal at 7.2 hours**

3. Is x^5 + x² + x? a polynomial? Explain why or why not.

**ANSWER:**

A polynomial is an algebraic expression of ordered addition, subtraction, and multiplication made up of variables, constants, and exponents.

Polynomials are made up of finite terms. Each term is an expression that contains one or more of the three elements they are made of variables, constants, or exponents.

In this case, for each term, the variable is x, the constant is 1, and the exponents are 5, 2, and 1, respectively.

This means that we have a sum of monomials, that is, that the expression is a polynomial.

Connect them in order: A to B, B to C, C to D, and then D back to A. What shape is created?

Five rays share a common endpoint. Set up an equation to find the value of x.

The **equation** that can be set up is, 2x° + 3x° + 36.5° + 36.5° + 2x° = 360°.

The value of x is: x = 41.

What are Angles around a Point?Angles that are formed around an **endpoint **but several rays will have a sum of 360 degrees when each of the angles formed around the **endpoint **is added together.

The diagram shows the angles that are formed by the five rays at a common **endpoint**. The angles are, 2x°, 3x°, 36.5°, 36.5°, and 2x°.

The sum of all these angles formed will give us 360 degrees. Therefore, the **equation** that would be created to find the value of x would be written as:

2x° + 3x° + 36.5° + 36.5° + 2x° = 360° [**equation** set up to find x]

Combine like terms

7x° + 73° = 360°

Subtract 73 from each side

7x° + 73° - 73° = 360° - 73° [subtraction property of equality]

7x = 287

Divide both sides by 7:

7x/7 = 287/7 [division property of equality]

x = 41

b) Add -2w to both sides.

2l + 2w + −2w = p +-2w

2l = p − 2w

Tina says, "The difference between any 2 consecutive square numbers is always odd." Is she correct? Yes No

yes she is correct it is always odd

**Answer:**

Yes

**Step-by-step explanation:**

Because they are consecutive, one is odd and one is even.

The square of an odd number is always odd

The square of an even number is always even

The difference between an odd number and an even number is always odd

Therefore, the difference between any 2 consecutive square numbers is always odd

Write an equation of the line passing through point P(-2, 6) that is parallel to the line x =-5 X Graph the equations of the lines to check that they are parallel.

The **equation** of the line passing through the** point P**(-2,6) that is parallel to the **line **x = -5 is x = -2 .

Write an equation that represents the line.

Use exact numbers.

**Answer:**

**y = -2x -3**

**Step-by-step explanation:**

To write an equation we need two points that the line cuts through.

we then use the formula: Gradient = Rise/Run

the points chosen are (0,-3) and (1,-5)

Gradient = (-5--3)/(1-0)

= -2

to write the equation we need one known point, gradient and one unknown point say (x,y).

we therefore use the formula for gradient/slope

G = Rise/Run

-2 = y+3/x-0

-2x = y + 3

**y = -2x -3**

**Answer:**

y = - 2x - 3

**Step-by-step explanation:**

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, - 5) ← 2 points on the line

m = [tex]\frac{-5-(-3)}{1-0}[/tex] = [tex]\frac{-5+3}{1}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

the line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

The area of one surface of a cube is 19,600 sq. cm. If the cube is filled with water how many bottles of 4 litres each can be filled from it?

**686 bottles** of 4 liters each can be filled from this **cube. **

We can solve this problem by following a few steps.

As we know that** a cube has 6 surfaces** and each surface has a geometrical shape of a square. We also know that each side of a square is the same.

So, the **surface area of a square ≡ Side × Side. **

Let's assume the side as z

Now, the area of this square ≡ z × z = z²

∴ z² = 19600, as per the question.

We have to solve the equation, z² = 19600 Or, z = 140 ( by doing root both sides)

Now we know the side of the cube, then the volume of this cube is z³.

As, we know the **volume of a cube ≡ side × side × side**, as the height of a cube is also identical.

Volume of the cube = 140³ = 2,744,000 cc

**1000 cc is considered as 1 liter**. Therefore, this cube consists of, 2,744,000/1000 = 2744 liter of water.

Each bottle consists of **4 liters **of water. Then we can fill, 2744/4 = **686 **bottles of water.

**Answer:**

a) x+4

b) a = 1, b = 10

**Step-by-step explanation:**

a) You can read the lenght of AB, which is 4 + x

b) The lenght of AD is 6+x

The area of the rectangle ABCD is lenght AB * lenght CD,

so (4+x)*(6+x) = 24 + 6x + 4x + x^2 = x^2 + 10x +24

Since this must equal 28, it follows that

x^2 + 10x + 24 = 28,

so 1*x^2 + 10x = 4

(note that 1*x^2 is just x^2)

so a = 1 and b = 10
