Answer:

Joseph tenía 240 soles

Step-by-step explanation:

Tenemos lo siguiente

Cantidad total = Cantidad gastada + Cantidad restante.

Sabemos que Cantidad gastada = 3/5 Cantidad restante y que Cantidad restante = Cantidad gastada + 60.

Sea x la cantidad gastada e y la cantidad restante. Tenemos las ecuaciones

x = \frac{3}{5}y, y = x+60

Reemplazando la segunda en la primera, tenemos que

x = \frac{3}{5}(x+60)= \frac{3}{5}x + 36 (aquí simplemente distribuímos la multiplicación.

Restando 3/5 x a ambos lados, tenemos que

x-\frac{3}{5}x = \frac{2}{5}x = 36

Multiplicando por 5 y dividiendo por dos ambos lados, tenemos que

x=\frac{5\cdot 36}{2} = 90

Es decir, Joseph gastó 90 soles. Entonces y = 90+60 = 150 soles.

Es decir, en total, Joseph tenía 150+90= 240 soles.

Betty has some hair ribbons that are blue. She has 19 blue ribbons. Three times the number of blue ribbons decreased by 5 is gre
likoan [24]

Answer:

3x-5> 6x- 14

Step-by-step explanation:

Let the blue ribbons be denoted by the letter x.

Then according to the given condition

3 times the blue ribbons = 3x

Decreased by 5 = 3x-5

is greater than

6 times the blue ribbons = 6x

decreased by 14 = 6x-14

Putting in one line

3x-5> 6x- 14

Solving the inequality

3x-5> 6x- 14

Taking both sides positive as in modulus

14-5 > 6x-3x

9> 3x

9/3 > x

3> x

Again solving for inequality

3x-5> 6x- 14

Taking one side negative that is mod

3x-5> -6x + 14

3x+ 6x > 14+5

9x> 19

x > 19/9

x > 2.11

so x lies between 2 and 3

3 > x > 2.11

Now putting the values for x= 19

3x-5> 6x- 14

57-5> 114-14

52 > 100 False

Now putting the values for x= 3

3x-5> 6x- 14

9-5> 18-14

4>4  False

Now putting the values for x= 2

3x-5> 6x- 14

6-5> 12-14

1> -2   True

There are 2 blue ribbons

What is the domain of the function shown in the table?
Basile [38]
The Domain of a function is described as the set of all the x values that a function can take.These are the allowable values of a function.

From the table we can see that the first column shows the x values for the function. So the set of all  values will be the Domain of the function.

Hence the Domain is {-2, -1, 0, 1}

So, option B gives the correct answer
