Answer:
43 feet
Step-by-step explanation:
How far is referring to the distance between the two numbers given.
In general, the distance between two numbers, a and b,
is given by |b-a| .
You have that you are finding the distance between -45.5 ft and -88.5 ft.
So the distance between those numbers is given by:
|-45.5-(-88.5)|
|-45.5+88.5|
|88.5-45.5|
|43.0|
|43|
43 (Since the number inside the | | has a distance of 43 from 0)
The distance between -45.5 ft and -88.5 ft is 43 ft.
Seconds because one second is less than one minute
I would say that B) is the correct answer hope this helps!!
Answer:
x= 2
Step-by-step explanation:
so expand the left side of the equation
9x+9= 25+x
and then group like terms( subtract 9 from both sides and also do same with x.
9x-x= 25-9
8x= 16
divide by 8 on both sides.
x=2
