Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.
18 * 2 = 36
36 * 2 = 72
There, it means that 18/2 will be subtracted from 20.
20 - 18/2
= 20 - 9
= 11
The next number in the sequence would be 11. Hope this helps!
Answer: x = 5
Step-by-step explanation:
x + 2x - x + 7 = 4x - x + 2
Left side:
x + 2x = 3x
3x - x = 2x (bring down the 7)
So 2x +7
Right side:
4x - x = 3x (bring down the 2)
So 3x + 2
2x + 7 = 3x + 2
Subtract 2 from both sides (7-2 and 2-2)
2x + 5 = 3x
Subtract 2x from 3x
5 = x
Answer:
Step-by-step explanation:
Given equation is
Factor denominators then solve by making denominators equal
take squar root of both sides
Hence final answer is .

<u>Proportional Model</u>
The number of miles m that Lexus can skateboard in t minutes can be modeled by:
m = kt
It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.
Substituting:
4 = k.20
Dividing by 20
Simplifying:
This produces the model
