Answer:
He will require 5400 seconds
Step-by-step explanation:
Given:
The total distance he has to cover = 48 miles
The speed he is moving = 32 mph
To find :
Time in seconds = ?
Solution:
As given in the question that he is moving with a constant speed of 32 mph and he has to cover a distance of 48 miles at this speed so we will be using distance formula for finding the time taken by him
Formula is
Distance = speed * time
here we have to find time so
Time = 
Putting in the values we get
Time = 
Dividing it gives us
Time = 1.5 hours
As we need the answer in seconds and we know that
one hour has = 3600 seconds
so
Time = 1.5 * 3600 seconds
Time = 5400 seconds

Answer: -2.145
Step-by-step explanation:
(3.2+4x)+(18.25+6x)=
Simplifying
(3.2 + 4x) + (18.25 + 6x) = 0
Remove parenthesis around (3.2 + 4x)
3.2 + 4x + (18.25 + 6x) = 0
Remove parenthesis around (18.25 + 6x)
3.2 + 4x + 18.25 + 6x = 0
Reorder the terms:
3.2 + 18.25 + 4x + 6x = 0
Combine like terms: 3.2 + 18.25 = 21.45
21.45 + 4x + 6x = 0
Combine like terms: 4x + 6x = 10x
21.45 + 10x = 0
Solving
21.45 + 10x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-21.45' to each side of the equation.
21.45 + -21.45 + 10x = 0 + -21.45
Combine like terms: 21.45 + -21.45 = 0
0 + 10x = 0 + -21.45
10x = 0 + -21.45
Combine like terms: 0 + -21.45 = -21.45
10x = -21.45
Divide each side by '10'.
x = -2.145
Simplifying
x = -2.145
