Please help will give 20 points to right answers (will give brainliest to very first correct answer) Tom walks 3.2 km every morn
nignag [31]
For this case we have the following conversions:
 1 mile = 1,609 km&#10;&#10;1 mile = 5,280 feet
 We must apply the conversions to move from kilometers to feet.
 We have then:
 (3.2) * (1 / 1,609) * (5280) = 10500.93226&#10;
 Rounding off we have:
 10501 feet
 Answer:
 
there are 10501 feet in 3.2 km

5 |2x + 6| = 25 what is x
Dvinal [7]

Step-by-step explanation:

මාපාංක සුලු කිරිම.

l xl means ± x .

then |2x+6| = ±(2x+6)

for positive no;

5 (2x+6) = 25

10x + 30 = 25

10x = -5

x = -1/2

for negative no;

5(-2x - 6) = 25

-10x - 30 = 25

-10x = 55

x = - 11/2

otherthan that I observed.

5 |2x + 6| means only consider about the positive number. i think it called as amplitude.

then you have to calculate by considering only considering plus value.

How ever in my openion is first method is correct. i have doubt about that. so you have to discuss your teacher dear. to find correct way.
