Hue is arranging chairs. She can form 2 rows of a given length with 2 chairs left over, or 6 rows of that same length if she get
Nady [450]
There are 7 chairs in each row length.
Step-by-step explanation:
Let number of chairs in 1 row be 'x'.
Let total number of chairs be 'y'.
Given:
Hue can form 6 rows of a given length with 3 chairs left over.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.
Framing in equation form we get.

Also Given:
Hue can form 8 rows of that same length if she gets 11 more chairs.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.
Framing in equation form we get.

From equation 1 and equation 2 we can say that L.H.S is same.
So according to law of transitivity we get;

Combining like terms we get;

Using Subtraction and Addition property we get;

Now Using Division Property we will divide both side by 2.

Hence there are 7 chairs in each row length.

HELPPPPPPPPPPP<br> Draw the graph of y = 2x + 3 on the grid
topjm [15]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=2x+3

This is the equation of the line

To graph a line we need two points

<em>Find the intercepts</em>

1) The y-intercept is the value of y when the value of x is equal to zero

For x=0

y=2(0)+3

y=3

The y-intercept is the point (0,3)

2) The x-intercept is the value of x when the value of y is equal to zero

For y=0

0=2x+3

x=-3/2=-1.5

The x-intercept is the point (-1.5,0)

To draw the graph of the line plot the intercepts and join the points

using a graphing tool

see the attached figure
