The list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have given a linear equation in one variable.

\rm \dfrac{1}{2}y + 3.2y = 20

After solving:

y = 5.40   (one solution)

\rm \dfrac{15}{2}+ 2z -\dfrac{1}{4}=4z+\dfrac{29}{4}  -2z

After solving:

\rm \dfrac{15}{2} -\dfrac{1}{4}=\dfrac{29}{4}

\rm \dfrac{29}{4}=\dfrac{29}{4} (Infinitely Many Solutions)

3z + 2.5 = 3.2 + 3z

2.5 = 3.2  (no solution)

Similarly, we can identify which equation has No Solution, One Solution, and Infinitely Many Solutions.

Thus, the list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.

Suppose you draw a card from a well-shuffled deck of 52 cards. Find each of the following odds.
garik1379 [7]
1)  number of cards that aren't : number of cards that are 3
we have 48 cards that arent 3 and 4 cards that are. that means that odds are:
12:1 of not drawing 3

2) fallow same logic. its just opposite.
1:12

3) same logic. but there are only 2 black 7 cards which means that odds are:
50:2 or
25:1

4) opposite of previous.

Answer:

josh vendió 17 libros recaudando 306 dolares .

jessica vendió  255 libros recaudando 4590 dolares.

Step-by-step explanation:

Sustituimos por variables :

libros que vendió Jessica = x

libros que vendió Josh = y

entonces:

x + y = 272

Jessica vendió 15 veces mas libros que josh:

x = 15y

Reemplazamos en la anteriior ecuacion:

15y +y = 272

16y = 272

y = 17

Reemplazamos en la primela ecuacion :

x + 17 = 272

x = 255
