Answer:
x = 3
Step-by-step explanation:
Once again we want to use the relationship stated earlier
Where A * B = C * D
Once again imagine that the segments in the given problem have letters
A = x
B = 12
C = x + 1
D = 9
Now we create an equation using the relationship
12 * x = 9(x+1)
now we solve using basic algebra
step 1 distribute the 9 to the x and the 1
9 * x = 9x
9 * 1 = 9
now we have 12x = 9x + 9
step 2 subtract 9x from each side
12x - 9x = 3x
9x - 9x cancels out
now we have 3x = 9
step 3 divide each side by 3
3x/3=x
9/3=3
we're left with x = 3
The inequality using variables x and y which satisfy the points are; y>-3x+3.
<h3>What is inequality?</h3>
Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given that the points (2,5) and (-3,-5) lie on the boundary line.
The system of inequality is given by:
y>-3x+3-
Now, the point that will lie in the solution set to the following system of inequality are the point that satisfies the inequality.
a) (6, 5)
when x=6 and y= 5
then we have:
y>-3x+3
6 > -3×5 + 3
6>- 15+3
5 > -12
This means that the point will lie in the solution set.
Also, (-2, -3) when x= -2 and y= -3
then we have:
5 > -3×(-2) + 3
5> 6 + 3
5> 9
Hence, the inequality using variables x and y which satisfy the points are; y>-3x+3.

Answer:
5 pieces
Step-by-step explanation:
Given:
Paula's painting has a perimeter of 1.22 meters.
She wants to put ribbon around the edge.
If the ribbon comes in pieces that are 25 centimeters long.
Question asked:
How many pieces of ribbon does she need to go all the way around her painting?
Solution:
Perimeter of painting = 1.22 meters
First of all we will convert it into centimeters:-
As we know:
1 meter = 100 centimeters
1.22 meters = 100
1.22 = 122 centimeters
Now, as given that ribbon comes in pieces of 25 cm long and total we should have 122 cm to go all the way around the painting.
Number of pieces of ribbon will be needed = 
Thus, she need 5 pieces of 25 cm long ribbon to go all the way around the painting.
<u>Note</u>:-This is by default understood that few length of 5th ribbon will be left over.
The answer is 1 because when you subtract 972 from 932 you get 40. Then u add 812 and 40 to see if u get 852 and u do, so add 40 to 852 and you get 892.
