Answer:
n=36
Step-by-step explanation:
To isolate n you need to subtract 15 from both sides giving you
2n=72
Then to further isolate n you need to divide 2 from both sides giving you the answer
n=36

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

I have to repost this because I was giving wrong answers. The instructions are to complete each proof using the properties of equality
Answer and Step-by-step explanation:
We are given:
[tex]\frac{2y-1}{-3} = 5[/tex]
First, we multiply both sides by -3.
2y - 1 = 15
Now we add 1 to both sides.
2y = 16
Finally, we divide by 2 to each side.
y = 8
We are given:
2x + 30 = -4(5x -2)
First we distribute the -4 to 5x and -2.
2x + 30 = -20x + 8
Now we subtract 8 from both sides.
2x + 22 = -20x
Now we subtract 2x from both sides.
22 = -22x
Finally, we divide by -22 to both sides.
-1 = x
Statements: Reasons:
Given
2y - 1 = 15 Multiplication Property of Equality

Morgan is reading a 326-page book. The table shows three different plans to finish the book.
Plan Pages to Read Each Day Number of Days Needed
A 10 33
B 20 ?
C 30 11
Part A
Using Plan B, how many days will it take Morgan to finish her book? Enter your answer in the box.
days
Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.
Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.
Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.
Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.
Divide 326 ÷ 20 to get 16 R6. Round the quotient to the next greater whole number.
E.
Divide 326 ÷ 20 to get 17 R6. Round the quotient to the next greater whole number.
Answer:
Part A
16 and 1/2 or 16 R6, 17 if you round up
Part B
Answer choices A and D are correct
