Answer:
D(x) = 3x
Step-by-step explanation:
Micah travels at a rate of 'x' feet over a specific period.
Linda travels at a rate of '2x' feet over that same period.
Since they are walking in opposite directions, the total distance they have walked towards one another (D) can be determined by adding both distances:
The expression that describes the number of feet they have walked toward one another is D(x) = 3x.
You would do 4 divided by 3. Which is 1.33 with repeating 3s. You would then round to the nearest hundredth which would 1.33. You can multiply 1.33 and 3 to check your work. Although it might not exactly 4 it is not that big of a deal.
Hope this helps!
I believe you could say the answer would be 34.651
The last digit could be any number from 1 to 4, since going to 5 would make it 34.66
<span>1.6625 x 10−21</span>
<span>mass of one helium atom x 250 </span>
Express 250 as 2.50.
(6.65 x 10−24)(2.50 x 102)

Answer: C. (-3, 9)
Step-by-step explanation:
Given
2|x-3|=12
Divide both sides by 2
2|x-3|/2=12/2
|x-3|=6
Take of absolute value sign (REMEMBER need to take into consideration of two conditions)
x-3=±6
1)x-3=6
x=9
2)x-3=-6
x=-3
**NOTE**: need to check each solution whether or not they are suitable
Hope this helps!! :)
