The building would be 100ft tall. You have to take 20/6 = ?/30 The difference between 6 and 30 is x5. Then all you have to do is 20x5 and you get 100ft.
Answer:
35 love
Step-by-step explanation:
Answer: x=4/7
Step-by-step explanation:
15-20x=x+3
15-20x-15=x+3-15
-20=x-12
-20x-x=x-12-x
-21x=-12
-21x/-21=-12/-21
x=4/7
Answer:
Table D
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
<u><em>Verify each case</em></u>
<em>Table A</em>
For x=1, y=3
Find the value of k
-----> 
For x=2, y=9
Find the value of k
-----> 
the values of k are different
therefore
The table A not represent a direct variation
<em>Table B</em>
For x=1, y=-5
Find the value of k
-----> 
For x=2, y=5
Find the value of k
-----> 
the values of k are different
therefore
The table B not represent a direct variation
<em>Table C</em>
For x=1, y=-18
Find the value of k
-----> 
For x=2, y=-9
Find the value of k
-----> 
the values of k are different
therefore
The table A not represent a direct variation
<em>Table D</em>
For x=1, y=4
Find the value of k
-----> 
For x=2, y=8
Find the value of k
-----> 
For x=3, y=12
Find the value of k
-----> 
All the values of k are equal
therefore
The table D represent a direct variation or proportional relationship
The linear equation is 
Answer:
2/5
Step-by-step explanation:
2 / 4 could be divided by two in both sides.
2 ÷ 2 = 1
4 ÷ 2 = 2
2/4 = 1/2
Same goes for 2/8 and 2/6
2 ÷ 2 = 1
8 ÷ 2 = 4
2/8 = 1/4
2 ÷ 2 = 1
6 ÷ 2 = 3
2/6 = 1/3
2/5 however, could not be divided by two on both sides because there is 5 and it is not a factor of 2. So it is in its simplest form
