Billy's Boat Rental Company charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Lisa's Boat Rental Company does not charge a yearly fee, but charges $14.75 every time a member rents a boat. How many times does a person have to rent a boat for the cost to be the same amount at both rental companies?

Answers

Step-by-step explanation:

we can proceed to model the cost of Billy's Boat Rental Company

let y be the cost

let x be the number of rentals

y=105+9.5x----1

Also, the cost of Billy's Boat Rental Company

y=14.75------2

the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"

we have to equate the two cost and solve for x

105+9.5x=14.75

105-14.75+9.5x=0

90.25+9.5x=0

9.5x=-90.25

divide both sides by 9.5 we have

x=-90.25/9.5

x=9.5

Answers

Answer: 6.89 per pound (assuming you meant which is the better deal)

Step-by-step explanation:

There are 16 ounces in a pound so you can multiply, 3.5 x 2 (since it is 3.5 for 8 ounces) to get 7. Therefore $6.89 for a pound is cheaper.

Lets solve your equation step-by-step

2(x+3)=x-4

Step 1 :Simplify both sides of the equation

2(x+3)=x-4

(2)(x)+(2)(3) =x+-4 (distribute)

2x+6=x+-4

2x+6=x-4

Step 2: Subtract x from both sides

2x+6-x=x-4-x

x+6=-4

Step 3: Subtract 6 from both sides

x+6-6=-4-6

Step-by-step explanation:

Guadalupe fue a la mercería a comprar 15.5 m de encaje blanco que necesita para la clase de costura. Si cada metro cuesta $5.60, ¿cuánto pagó por todo el encaje que necesita?

También pidió 4.75 m de cinta azul que le encargó su mamá. Si el metro cuesta $8.80 y su mamá le dio $40.00, ¿le alcanzará el dinero para comprarla?

¿Le falta o le sobra dinero? ¿Cuánto?​

Answers

Answer:

a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Step-by-step explanation:

a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado ([tex]n[/tex]), medido en metros, y el coste unitario ([tex]c[/tex]), medido en pesos por metro:

[tex]C = c\cdot n[/tex] (Eq. 1)

Si conocemos que [tex]c = 5.60\,\frac{\$}{m}[/tex] y [tex]n = 15.5\,m[/tex], entonces tenemos que:

[tex]C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)[/tex]

[tex]C = \$ \,86.8[/tex]

Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) El coste total de la cinta azul es: ([tex]c = 8.80\,\frac{\$}{m}[/tex], [tex]n = 4.75\,m[/tex])

[tex]C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)[/tex]

[tex]C = \$\,41.8[/tex]

Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Now locate the y-axis (vertical) location of point P, starting from zero

Point P's y-axis = 3

Combine the two axes in a coordinate equation.

Point P = (-4, 3)

I need help with angles

Answers

Answer:

The value of x is 8

The measure of angle A is 42 degrees

A and B are consecutive interior angles

Step-by-step explanation:

Since A and B are consecutive interior angles you combine both equations and have it equal to 180

16x+10+5x+2=180

21x+12=180

21x=168

x=8

Plug 8 into the equation across from A

16(8) +10

128+10

138 degrees

Since angle A is supplementary you do 180-138= 42 degrees
