Classrooms have a capacity of either 30 or 31 students. If 307 students are assigned to rooms that are to be filled to capacity,

There are now 7 classrooms of 31 and 3 of 30.

<h3>What is liner equation?</h3>

A linear equation in mathematics is an equation that can be written as display style a 1x 1+ldots +a nx n+b=0, where x 1, dots, x n are the variables, and display style b, a 1, ldots, a n are the coefficients, which are frequently real integers.

<h3>According to the given information:</h3>

Madison, we first have to add 30 + 31 = 61.

How many times does 61 go into 307

Five,

because 61 x 5 = 305.

This means there are 5 of each classroom.

We still have two students left over, though, so they will have to be added to two of the 30 rooms,

so there are now 7 classrooms of 31 and 3 of 30.

Write this as an equation in point-slope form Please answer as quickly as possible. 50 pts!!!!!

jeka57 [31]

The answer is: "  y − 1 = - 3(x + 2) " .
__________________________________________________________

Explanations:
__________________________________________________________

<u>Note</u>: The "point-slope form" of the equation of a line is:

→ " y − y₁ = m(x −x₁) " .

We are given the slope, m" , is: " - 3 " ;

We are given a point on the line [on the graph that is represented by this equation]; with the coordinates: " (-2 , 1) " ;

→ which is in the format: " (x₁ , y₁) " ;

→ As such: " x₁ = -2 " ; " y₁ = 1 " ;
_____________________________________________________
As aforementioned, the equation of a line in "point-slope form" ; is:
_________________________________________________________
→ " y − y₁ = m(x − x₁) " ;

in which:

→ "(x₁ , y₁) " represents the coordinates of a given point on the [line of the graph represented by the equation] ; AND:

→ " m " = the slope of the line [represented by the equation] " ;

We proceed by substituting our known values for "m" ; "y₁" ; and "x₁" :

→ " y − 1 = - 3(x − (-2) ) " ;
_______________________________________________________
→ Rewrite as:
_______________________________________________________
→ " y − 1 = - 3(x + 2) " ;

→ which is our answer; since it is written in "point-slope form" .

1. Mrs. Verner's class has

Dmitrij [34]

Answer:

46.7%

Step-by-step explanation:

Given:

Total number of students in Mrs. Verner's class = 15

Number of girls = 8

To find: percentage are boys

Solution:

Percentage of boys = ( Number of boys / Total number of students ) × 100

Number of boys = Total number of students - Number of girls = 15 - 8 = 7

So,

Percentage of boys = $\frac{7}{15}$ × 100 = 46.7%

You are buying an area rug for your bedroom. The area of your room you want to cover is 40 feet squared. You find that the lengt

Kamila [148]

The length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.

Area is defined as the space covered by any object in the two dimensional plane. Here it is given that the area of the rug should be 40 square feet and the length of the rug is 3 less then its width.

So to find out the length and the width we will form an equation.

Let the width is = x feet

So the length will be = x-3 feet

Now the area will be

$x(x-3)=40$
