Which algebraic expression represents the difference of fifty four and seven times a number

Answer:

corrieron 50 kilómetros de la escuela a la casa

Answer:

ok so the angles are

60

90

30

so we can just use the formulas

y=15

x=25.981 or 26

Answer:

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:

the answer is a

Step-by-step explanation:

formula= (angle / 360) x π x (diameter / 2)^2

i this case we have the radius already so

= (240/360)*(pi)*(11)^2

=2/3(3.14)*(121)

= around 253.29

= which leads me to believe a is correct

Answer:

Solution given;

angle =240°

radius [r]=11cm

we have

length of arc =240°/360°×π*r²

=240°/360°×2×3.14*11²=253.29cm²

length of the arc is 253.29cm².

Answer:

5725.65cm

Step-by-step explanation:

Because there are 10mm in every 1cm, we start by taking the 57256.5mm and divide that by 10, effectively moving the decimal point to the left by one number, resulting in 5725.65cm.

Answer: Use division to convert the fraction to a decimal: 1/4 = 1 ÷ 4 = 0.25.

Multiply by 100 to get percent value: 0.25 × 100 = 25%

Answer:

x=16

Step-by-step explanation:

let:

> x be one number

> y be the other number

system of Equations:

> x+y=8

> x-y=24

Using elimination method the y's cancel each other out, and we are left with

2x = 32

divide by 2 on both sides to get x by itself

AND

x=16

Answer:

$840 dollars

Step-by-step explanation:

Divide 540 by 9 to get the cost of 1 book then multiply it by 14

Answer:

$840

Step-by-step explanation:

[tex]\frac{14}{9}: \frac{y}{540}[/tex]

y × 9 = 540 × 14

9y = 7560

9y ÷ 9 = 7560 ÷ 9

y = 840

slope intercept form = y=mx+b

m= slope

b= y-intercept

the slope is rise over run, so if the points are (1, -6) and (5, -6), the slope is 0

the y intercept is -6

y = 0x-6

or

y = -6

Answer:

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

Step-by-step explanation:

Things you should before solving this question :-

where a and b are any two variables.

SIMPLIFYING THE EXPRESSION

[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} \\ [/tex]

using the identity discussed above

[tex] \frac{ (x + 3)(x - 3) }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} [/tex]

simplifying 3x² + 8x - 3

[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 9x -x - 3} \div \frac{x - 3}{x + 2} [/tex]

as 8x can be written as 9x - x

[tex] \frac{ (x - 3)(x + 3) }{3 {x}(x + 3) - 1(x + 3)} \div \frac{x - 3}{x + 2} \\ \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \div \frac{x - 3}{x + 2} [/tex]

flipping the fraction that follows division sign and inserting multiply in place of divide

[tex] \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \times \frac{x + 2}{x - 3} [/tex]

canceling (x - 3) and (x + 3) as they're common in both denominator and numerator

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

Answer:

The Answer is B.

Step-by-step explanation:

B:  5 Brands and 4 Sizes

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

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:

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)

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
