It costs $13 to rent a canoe and $5.50 to use the canoe for an hour. You have $29.50. Write an equation that represents the number $h$ of hours you can rent the canoe.

Answer:

the answer is 65

Step-by-step explanation:

13x5=65

12 feet is the distance along the ground from the truck to the end of the ramp.

What is Pythagorean Theorem?

For a right-angled triangle

(base)²+(height)²=(hypotenuse)².

The ramp makes a right-angled triangle with the truck and the ground refer to the supported diagram.

Let x be the distance along the ground from the truck to the end of the ramp. Then

x²+5²=13²

⇒x²=13²-5²

⇒x²=169-25=144=12²

Hence, 12 feet is the distance along the ground from the truck to the end of the ramp.

Answer:

The number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.

Step-by-step explanation:

It is provided that on Sunday Querida gave away about 52 coupons an hour.

Compute the number of coupons given away for different hours as follows:

    Number of hours :    1         2          3          4

Number of Coupons :   52      104      156      208

Compute the number of coupons given away per hour provided that Querida worked 2 hours, 3 hours and 4 hours on Sunday as follows:

[tex]\text{Number of coupons given away per hour}=\frac{104}{2}=52\ \text{coupon/hour}[/tex]

[tex]\text{Number of coupons given away per hour}=\frac{156}{3}=52\ \text{coupon/hour}[/tex]

[tex]\text{Number of coupons given away per hour}=\frac{208}{4}=52\ \text{coupon/hour}[/tex]

Thus, the number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.

Answer:

h+6/5=3

We move all terms to the left:

h+6/5-(3)=0

determiningTheFunctionDomain

h-3+6/5=0

We multiply all the terms by the denominator

h*5+6-3*5=0

We add all the numbers together, and all the variables

h*5-9=0

Wy multiply elements

5h-9=0

We move all terms containing h to the left, all other terms to the right

5h=9

h=9/5

h=1+4/5

Step-by-step explanation:

Answer:

We are to find x and y in this equation.

5x+4y= -20.

- 5x+12y= -10.

which is y=5/4 or 1.25.

then substitute y=1.25 into eqtn I.

5x+4(1.25)=-20.

5x+5= -20.

5x=-20-5.

5x= -25.

x= -5.

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{14 {x}^{2} - 96}{ {x}^{4} - 13 {x}^{2} + 36}}}}}} [/tex]

Step-by-step explanation:

[tex] \sf{ \frac{2}{x - 2} + \frac{1}{x - 3} - \frac{2}{ x + 2} - \frac{1}{ x + 3}}[/tex]

⇒[tex]\sf{ \frac{2(x - 3)(x + 3)(x + 2) + (x - 2)(x + 2)(x + 3) - 2(x - 2)(x - 3)(x + 3) - (x - 2)(x + 2)(x - 3)}{(x - 2)(x - 3)(x + 2)(x + 3)}} [/tex]

Use the formula : a² - b² = ( a + b ) ( a - b )

⇒[tex] \sf{ \frac{2( {x}^{2} - 9)(x + 2) + ( {x}^{2} - 4)(x + 3) - (2x - 4)( {x}^{2} - 9) - ( {x}^{2} - 4)(x - 3) }{( {x}^{2} - 4)( {x}^{2} - 9)}} [/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{ \frac{(2 {x}^{2} - 18)(x + 2) + ( {x}^{2} - 4)(x + 3) - (2x - 4)( {x}^{2} - 9) - ( {x}^{2} - 4)(x - 3)}{( {x}^{2} - 4)( {x}^{2} - 9) } }[/tex]

Multiply the algebraic expressions

⇒[tex] \sf{ \frac{2 {x}^{3} + 4 {x}^{2} - 18x - 36 + {x}^{3} + 3 {x}^{2} - 4x - 12 - (2 {x}^{3} - 18x - 4 {x}^{2} + 36) - ( {x}^{3} - 3 {x}^{2} - 4x + 12) } {( {x}^{2} - 4)( {x}^{2} - 9)} }[/tex]

When there is a ( - ) in front of an expression, change the sign of each term in the expression

⇒[tex] \sf{ \frac{2 {x}^{3} + 4 {x}^{2} - 18x - 36 + {x}^{3} + 3 {x}^{2} - 4x - 12 - 2 {x}^{3} + 18x + 4 {x}^{2} - 36 - {x}^{3} + 3 {x}^{2} + 4x - 12}{( {x}^{2} - 4)( {x}^{2} - 9) } }[/tex]

Since two opposites add up to zero, it would be better to remove them from the expression

⇒[tex] \sf{ \frac{4 {x}^{2} - 36 + 3 {x}^{2} - 12 + 4 {x}^{2} - 36 + 3 {x}^{2} - 12}{( {x}^{2} - 4)( {x}^{2} - 9)} }[/tex]

Answer:

x=1

Step-by-step explanation:

First you distribute the 3 to 5x and 1 to get 15x+3=18x

Then you subtract 15x from 18x and get 3x

Lastly you divide 3 by 3 to separate the 3 and x and get x=1.

Answer:

x=30

Step-by-step explanation:

          3

Simplify   —

           5

 3          

 (— • x) -  18  = 0  

  5          

STEP

  Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

         18     18 • 5

   18 =  ——  =  ——————

         1        5    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3x - (18 • 5)     3x - 90

—————————————  =  ———————

      5              5  

Pull out like factors :

  3x - 90  =   3 • (x - 30)

 3 • (x - 30)

 ————————————  = 0  

      5      

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 3•(x-30)

 ———————— • 5 = 0 • 5

    5    

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  3  •  (x-30)  = 0

Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

  Solve  :    x-30 = 0  

Add  30  to both sides of the equation :  

                     x = 30

One solution was found :

x = 30

Answer:

c^10 d^18

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) A = x

Flower garden is in rectangular shape. In rectangle, opposite sides are equal.

2)  The entire garden is in rectangular shape. In rectangle, opposite sides are equal.

B + x+ 4 = 10x + 6

Take x and 4 to other side to find the value of B. When taking to other side of equal to sign, the sign of x and 4 will change

B = 10x + 6 - x  - 4

B = 10x - x + 6 - 4   {Combine like terms}

B = 9x + 2

3)  C + x -2 = 5x -3

   C = 5x - 3 - x  +2

C = 5x -x - 3 + 2

C = 4x - 1

4) Area of Vegetable garden = length * width

                                                = (5x - 3) * (9x + 2)

Use FOIL method

                                               = 5x *9x  + 5x*2  + (-3)*9x + (-3)*2

                                                = 45x²  + 10x - 27x - 6  

                                                = 45x² - 17x - 6

Answer

D) the state

I took on Test:))))))

In a communist command economy, workers are employed by the state. Hence, option D is correct.

A command system, usually referred to as communism, is an economic system in which the government controls the majority of the factors of production, decides how resources will be distributed, and determines what goods and services will be offered. Karl Marx and Frederick Engels were the principal architects of communist theory.

A communist political system includes a command economy, whereas capitalist countries have a free market. A command economy might take the form of socialism or communism. In all three, the government is in charge of the nation's enterprises, resources, and economic activities.

Thus, option D is correct.

Answer: 200 literes will be used in an hour

Step-by-step explanation:

1. 150 divided by 45 mins = 3.3 recurring

2. 3.3 recurring times 60 ( 60 mins in an hour) = 200

The amount of the petrol will be consumed in one hour will be 200 liters.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A car uses 150 liters of petrol in 45 minutes.

Then the rate at which the amount of petrol is consumed in liters per minutes will be

⇒ 150 / 45

⇒ 10 / 3  Liters per minutes

We know that there are 60 minutes in one hour.

Then the amount of the petrol will be consumed in one hour will be

⇒ (10 / 3) x 60

⇒ 10 x 20

⇒ 200 liters

Thus, the amount of the petrol will be consumed in one hour will be 200 liters.
