Answer:
5 units
Step-by-step explanation:
The distance between them is 5 units.
7 + 14
7(1 + 2)
44 - 11
11( 4 - 1)
18 - 12
6(3 - 2)
70 + 95
5(14 + 19)
60 - 36
12(5 - 3)
100 - 80
20(5 - 4)
Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>

Answer:
38 pages per hour
Step-by-step explanation:
Rate of reading = 
By substituting the given values in the question,
Total number of pages read by Davida = 
= 
Time taken by Davida = 45 minutes
Since, 1 minute = 
hours
Therefore, 45 minutes = 
hours
Rate of reading = 
= 
= 38 pages per hour
Therefore, rate of reading by Davida is 38 pages per hour.
