The sum of the digits of a certain two digit number is 8. By reversing the digits the number is increased by 18. What is the number?

Answer:

a) A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.

b) Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.

Step-by-step explanation:

a) Antonio, Lucas y Darío compraron un refresco, el cual reparten en tres partes iguales. Por tanto, la fracción de litro para cada persona es la capacidad del refresco dividido por el número de personas. Es decir:

[tex]x = \frac{\frac{5}{2}\,L }{3}[/tex]

[tex]x = \frac{5}{6}\,L[/tex]

A Antonio, Lucas y Darío le corresponde cada uno [tex]\frac{5}{6}[/tex] litros.

b) En primer lugar calculamos la fracción correspondiente a cuatro personas:

[tex]x = \frac{\frac{5}{2}\,L }{4}[/tex]

[tex]x = \frac{5}{8}\,L[/tex]

Ahora, procedemos a calcular la diferencia entre el escenario calculado en a) y el resultado anterior:

[tex]\Delta x = \frac{5}{6}\,L-\frac{5}{8}\,L[/tex]

[tex]\Delta x = \frac{40-30}{48} \,L[/tex]

[tex]\Delta x = \frac{10}{48}\,L[/tex]

[tex]\Delta x = \frac{5}{24}\,L[/tex]

Este resultado corresponde a la fracción que Antonio, Lucas y Darío deben convidar cada uno a Benjamín. Entonces, Antonio, Lucas y Benjamín deben convidar cada uno [tex]\frac{5}{24}[/tex] litros.

Answer:

Your slope would be 3.

Step-by-step explanation:

To find the slope from two points, you would need to use the formula: y2-y1/x2-x1

In this case, the equation would look like -2-7/5-8.

-2 - 7 = -9

5 - 8 = -3

-9/-3 = 3

Slope: 3

Answer:

ITS THE SECOND ONE

Step-by-step explanation:

Answer: x=25

Step-by-step explanation:

Simplifying

(2x + -10) = (65 + -1x)

Reorder the terms:

(-10 + 2x) = (65 + -1x)

Remove parenthesis around (-10 + 2x)

-10 + 2x = (65 + -1x)

Remove parenthesis around (65 + -1x)

-10 + 2x = 65 + -1x

Solving

-10 + 2x = 65 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

-10 + 2x + x = 65 + -1x + x

Combine like terms: 2x + x = 3x

-10 + 3x = 65 + -1x + x

Combine like terms: -1x + x = 0

-10 + 3x = 65 + 0

-10 + 3x = 65

Add '10' to each side of the equation.

-10 + 10 + 3x = 65 + 10

Combine like terms: -10 + 10 = 0

0 + 3x = 65 + 10

3x = 65 + 10

Combine like terms: 65 + 10 = 75

3x = 75

Divide each side by '3'.

x = 25

Simplifying

x = 25

Answer:

360ft^2

Step-by-step explanation:

We know that the height is always 8 ft. So lets find the area of two of the 4 walls.

We multiply by 2 because there are two of the same wall.

2(8ft x 10ft) = 160ft^2

Now lets find the area of the other wall.

2(8ft x 15ft) = 240ft^2

Now we add it up

160 + 240 = 400

400ft^2

But wait! We aren't done yet! We still have to subtract out the door and window which is 60ft^2.

400 - 60 = 360

360ft^2

Answer:

2nd one

Step-by-step explanation:

Graph-2 is correct line that represents the parking charge of the public garage.

A linear equation is an equation where the variable has the highest degree of 1.

Given, a public parking garage charges $5, plus an additional $2 per hour.

For 1 hour, the total cost will be = $(5 + 2 × 1) = $7.

For 2 hours, the total cost will be = $(5 + 2 × 2) = $9.

For 3 hours, the total cost will be = $(5 + 2 × 3) = $11.

For 4 hours, the total cost will be = $(5 + 2 × 4) = $13.

For 5 hours, the total cost will be = $(5 + 2 × 5) = $15.

Here, the increase in parking cost is in the form of linear equation and it increases $2 with the increase in every hour.

Therefore, graph-2 represents the actual line of cost of the parking charge and time.

Step-by-step explanation:

let the one number be X.

and

second one 1/3

then

1/3 +X = 5/9

X = 5/9-1/3

X =( 5-3) /9

X = 2/9 Ans

Answer:

The other number will be 2/9.

Step-by-step explanation:

Let the second fraction be x :

[tex] \frac{1}{3} + x = \frac{5}{9} [/tex]

[tex]x = \frac{5}{9} - \frac{1}{3} [/tex]

[tex]x = \frac{5}{9} - \frac{3}{9} [/tex]

Answer:

2m-4

Step-by-step explanation:

double both of them and just simplify

the first one will become (6m-12) and the second will become (-4m+8)

subtract 6m and -4m so it's 2m

subtract -12 and 8 so it's -4

so the answer is 2m-4

Answer:

B. 2m - 4

Step-by-step explanation:

When simplifying the expression (3m - 6) + (3m - 6) + (-2m + 4 ) + (-2m + 4) while trying to find the perimeter, you will find your answer to be 2m - 4.

Answer:

I think it would be y + 6 = x + 3

Step-by-step explanation:

Because they both have to be positive because the points are positive. Also the slope has to be 1 so x cannot have a number with it or else it changes the value.

Answer/Step-by-step explanation:

Segment AE is a radius of the circle with center of A.

Any segment that has its origin from the center of the Circle, A, and meets at any point along the circumference of the circle, is equally a radius, and would have the same length as segment AE.

Thus:

a. Length of segment CD:

Segment CD is half of the circle. So it is the diameter of the circle.

Diameter of a circle = 2 × length of the radius.

Therefore,

CD = 2 × AE

CD = 2 × 5 (substitution)

CD = 10 cm

b. AB is a radius.

Therefore, AB = AE

AB = 5 cm

c. Any of these segments are also radius of the circle and also have the same length as segment AB:

Segment AG,

Segment AD

Segment FA

Segment AC
