Answer:
19v
Step-by-step explanation:
3v, 7v, and 9v all have the same variable, therefor, you can add all of them up as you would regular numbers, you just have to add "v" at the end.
Answer:
Disagree
Step-by-step explanation:
You can solve this problem by doing as follows:
9x+15=3x+15
-3x -3x
=
6x+15=15
-15 -15
=
6x=0
Although x=0, x=0 is still a solution to the problem.
First, you can factor them into (x-8)(x+9)=0 then set x-8=0 and x+9=0, in which you get X = 8 or X = -9
Answer:
option-C
Step-by-step explanation:
We are given
At 9:00 a.m., a wind speed of 20 miles per hour was recorded
So, initial wind speed =20 miles per hour
Each measurement showed an increase in wind speed of 3 miles per hour
The strongest wind was recorded at 4:00 p.m
so,
top wind speed = initial wind speed + ( total number of hours between 9:00 am and 4:00 pm)*(change in wind speed)
top wind speed = 20 mph+(16-9)*3

miles per hour
Since, change in wind speed and initial wind speed are constant
but the number of hours it took for the wind speed to reach its minimum for the day can be changed
so, most important variables is
the number of hours it took for the wind speed to reach its minimum for the day can be changed
