Answer:

$14.8

Step-by-step explanation:

There is a mistype in the question. It should say: ... <em>si cada uno de ellos hicieron una contribución de </em><em>dieciseis</em><em> pesos...</em>

So if everybody contributes $14, they make a total of 14*x, where x denotes the number of students. In this scenario, $4 are left, calling y to the cost of the trip, then:

14*x = y - 4 (eq. 1)

In the other scenario, everybody contributes $16 and $6 are in excess, so

16*x = y + 6 (eq. 2)

subtracting eq. 1 to eq. 2:

16*x - 14*x = y + 6 - (y - 4)

2*x =  y + 6 - y + 4

2*x = 10

x = 10/2 = 5

Replacing this value in eq. 1:

14*5 = y - 4

70 + 4 = y

y = $74

If every student pays: 74/5 =  $14.8, then they would get altogether the exact cost of the trip

How can you compare and order integers? Provide an example
antiseptic1488 [7]

You can both compare and order integers by subtracting them:

  • If the difference is zero, as the name suggests...there's no difference! So, the integers are the same. For example, you have 3-3=0,\ 6-6=0,\ -17-(-17)=0
  • If the difference is positive, then the first integer is bigger than the second. For example: 5-2=3>0,\ 18-(-2)=20>0,\ -3-(-10)=7>0 and we deduce that 5 is greater than 2, 18 is greater than -2 and -3 is greater than -10
  • If the difference is negative, then the first integer is less than the first. For example, if we invert the previous differences, we have 2-5=-3 and we deduce that 2 is less than 5, -2 is less than 18 and than -10 is less than -3

Which is the graph of a logarithmic function?
Reika [66]

The domain and range of the graph of a logarithmic function are;

  • Domain; 0 < x < +∞

  • Range; The set of real numbers.

<h3>How can the graph that correctly represents a logarithmic function be selected?</h3>

The basic equation of a logarithmic function can be presented in the form;

y =  log_{b}(x)

Where;

b > 0, and b ≠ 1, given that we have;

y =  log_{1}(x)

{1}^{y}  = 1

The inverse of the logarithmic function is the exponential function presented as follows;

x =  {b}^{y}

Given that <em>b</em> > 0, we have;

{b}^{y}  = x > 0

Therefore, the graph of a logarithmic function has only positive x-values

The graph of a logarithmic function is one with a domain and range defined as follows;

Domain; 0 < x < +∞

Range; -∞ < y < +∞, which is the set of real numbers.

The correct option therefore has a domain as <em>x </em>> 0 and range as the set of all real numbers.

Find the value of x, y, and z in the rhombus below.
34kurt

Answer:

Step-by-step explanation:

For a rhombus, the opposite angles are equal:

74=5y+9

5y=65

y=13

For a rhombus, the adjacent angles are supplementary:

74+(z-10)=180

z-10=106

z=116

74+(x+7)=180

x+7=106

x=99

How do I solve this?<br><br> x+1/x-2 &gt; 0
Eduardwww [97]

Answer:

x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)

Step-by-step explanation:

\frac{x+1}{x-2}>0\\ \\x+1>0=>x>-1\\\\x-2>0=>x>2

x ∈ (+ 2 ; +oo)

x+1x

x ∈ (-oo ; - 1)

x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)

Solve for x: 2x/5=12/8
Anika [276]

Answer:

x = 3\frac{3}{4}

Step-by-step explanation:

First, you have to leave 2x by itself on the left side of the equation:

2x = 60/8

Then divide,

x = 15/4

Simplified fraction: x = 3\frac{3}{4}
