La cantidad de dinero que tiene Alicia es 6 pesos.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones lineales, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema. Es decir, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en las ecuaciones.

Siendo:

Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{x-2=2*y} \atop {x-4=y}} \right.[/tex]

Sustituyendo la ecuación 2 en la primer ecuación:

x-2= 2*(x -4)

Resolviendo:

x -2= 2*x -2*4

x -2= 2*x -8

-2 + 8= 2*x -x

6= x

Entonces, la cantidad de dinero que tiene Alicia es 6 pesos.

Answer:

below

Step-by-step explanation:

that is the procedure above

fraction of arc RS

ANGLE RcS = 60 °

60°/360°

=1/6

therefore the total fraction is 1/6

The fraction of the whole circle is arc RS = (1/6)

approximate circumference of the circle = 31.4 cm

approximate length of arc RS = 5.23 cm

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

As per the given data:

Radius of circle with center C = 5 cm

central angle = 60°

∠RCS = 60°

To find out the fraction of the whole circle is arc RS:

arc length = radius × θ {θ is in radians}

∠RCS = 60° = 60° × (π/180°) = π/3

fraction of the whole circle = arc length / circumference

= [tex]\frac{r \times \frac{\pi}{3}}{2\pi r}[/tex] = (1/6)

approximate circumference of the circle = 2πr

= 2π(5)

= 31.4 cm

approximate length of arc RS = r × θ

= 5 × (π/3)

= 5.23 cm

Hence, the fraction of the whole circle is arc RS = (1/6)

approximate circumference of the circle = 31.4 cm

approximate length of arc RS = 5.23 cm

Answer:

-2

Step-by-step explanation:

they are parallel so same slope but different y intercepts

Part (a)

Refer to the diagram below to see the two triangles separated.

================================================

Part (b)

If the 3 meter portion is perpendicular to the horizontal portion, then the triangles are similar. We can prove this using the AA similarity theorem. One pair of angles would be the shared overlapping 25 degree angles. The other pair of congruent angles would be the two 90 degree angles. We only need two pairs of congruent angles to use AA. You could use three pairs (and the aptly named AAA theorem) but that's overkill in my book.

================================================

Part (c)

There are a few ways to approach this, but one way is shown below

y/3 = (8.4+6.6)/(6.6)

y/3 = 15/(6.6)

6.6y = 3*15 .......... cross multiply

6.6y = 45

y = 45/(6.6)

y = 6.81818 approximately

When rounding to one decimal place, we get y = 6.8

The number of 10 bouquets sold should you expect to be lily bouquets will be 5.

A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other.

Given that a florist sold 16 flower bouquets yesterday, including 8 lily bouquets. Based on past data. The number of bouquets sold is 10.

The number of the Lily bouquets will be calculated as:-

Number = ( 8 / 16 ) x 10

Number = ( 1 / 2)  x 10

Number = 5

Answer:

12,400

Step-by-step explanation:

Let the current employees be x

65% increase in number = 0.65x

If the total number of employees after the increase is 20,460, then;

x + 0.65x = 20,460

1.65x = 20,460

x = 20,460/1.65

x = 12,400

Hence the current number of employees is 12,400

Answer:

Step-by-step explanation:

the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000

the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.

so,

I think, this is a very significant number of truck cost compared with gas cost

for the best deal, the first truck is the best choice.

Answer:

buy truck 2  since it cheaper

, if u do it in a graph after they intersect usee that truck num 1 increases while truck num 2 decreases

Step-by-step explanation:

1.

First Truck: Y = 0.31x + 145,000

Second Truck: Y = 0.27x + 160,000

2.

Y = 0.31x + 145,000

Y = 0.27x + 160,000

- 0.31x + y = 145,000

- 0.27x + y = 160,000

- 0.31x + y = 145000

0.27x – y = -160000

- 0.04 = -15000

X=375000

- 0.31 x 375000 + y =145000

Y = 261250

(x , y) = (375000 , 261250)
