solve nt+6-xt=s for t

Answers

Answer:

[tex]t=\frac{s-6}{n-x}[/tex]

Step-by-step explanation:

[tex]nt+6-xt=s[/tex]

[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]

[tex]nt+6-xt-6=s-6[/tex]

[tex]Simplify[/tex]

[tex]nt-xt=s-6[/tex]

[tex]nt-xt[/tex]

[tex]=t\left(n-x\right)[/tex]

[tex]t\left(n-x\right)=s-6[/tex]

[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]

[tex]t=\frac{s-6}{n-x}[/tex]

Therefor the value of t after arrangement is t = (s-6)/(n-x)

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.

Given equation is  nt+6-xt=s

Now solving for t by separately variables and constant :

 nt+6-xt=s

t(n-x) = s-6

t = (s-6)/(n-x)

Therefor the value of t after arrangement is t = (s-6)/(n-x)

1st box: 2

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

All you have to do to find y is plug in the values of x given in the chart and onto the equation

1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2

(-1, 2)

2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5

(0,5)

3rd: x = 1 y= 8

4th: x = 2 y= 11

5th: x = 3 y= 14

Find the inverse for this relation: { (1, -3), (-2, 3), (5, 1), (6, 4) }

Answers

Answer:

(-3,1), (3,-2), (1,5), (4,6)

Step-by-step explanation:

For finding and inverse of a relationship, you simply just need to swap the x and y values. So the x will go into the y value and the y value will go into the x value.  

The inverse relation for the given relation is  {(-3, 1), (3, -2), (5, 1), (6, 4)}.

What is relation?

A relation in mathematics can be defined as a set of a pair of elements belonging to each set. It is also called as a mapping from one set to the other.

The given relation is { (1, -3), (-2, 3), (5, 1), (6, 4) }.

The domain of the given relation is set of all the first elements of each pair and the range is the set of all the second elements of each pair.

The range and domain set can be written as,

Domain = {1 , -2, 5, 6 }

Range =   {-3, 3, 1, 4}

In order to find the inverse relation the domain and range sets sre interchanged.

Thus, the inverse relation for the given relation can be written as,

{(-3, 1), (3, -2), (5, 1), (6, 4)} .

Hence, the inverse relation is given as {(-3, 1), (3, -2), (5, 1), (6, 4)}.

Monica uso 1,2 litros de leche para hacer 12 flanes iguales ¿cuantos litros de leche necesitaria para hacer 60 flanes? ¿cuantos flanes haria con 0,5 decalitros de leche?

Answers

Answer:

1. 6 L de leche.

2. 50 flanes.

Step-by-step explanation:

1. Determinación del volumen (en litros) necesario para realizar 60 natillas.

De la pregunta dada arriba,

Monica usó 1.2 L de leche para hacer 12 natillas iguales.

Por lo tanto, usará xL de leche para hacer 60 natillas, es decir

xL de leche = (1.2 × 60) / 12

xL de leche = 6

Por lo tanto, necesitará 6 L de leche para hacer 60 natillas.

2. Determinación del número de flanes (natillas) que se pueden producir utilizando 0,5 decalitros de leche.

Empezaremos por convertir 0,5 decalitros (deca) a litro (L).

Esto se puede obtener de la siguiente manera:

1 deca = 10 L

Por lo tanto,

0.5 deca = 0.5 deca × 10 L / 1 deca

0,5 deca = 5 L

Por tanto, 0,5 deca equivale a 5 L.

Finalmente, determinaremos el número de flanes (natillas) que se pueden obtener a partir de 0.5 deca (es decir, 5 L) como se muestra a continuación:

Monica usó 1.2 L de leche para hacer 12 natillas iguales.

Por lo tanto, usará 5 L de leche para producir = (5 × 12) /1.2 = 50 natillas

Por lo tanto, puede hacer 50 flanes (natillas) usando 0.5 deca (es decir, 5 L).
