Answer:
First one: 9 units
Second one: |2.5|, |-3|, |3.3|, |-4|
Step-by-step explanation:
9 units not negative 9 since you are counting the distance, not to or from, and the second one is the absolute value with each one, to simplify:
|-3|=3
|2.5|=2.5
|-4|=4
|3.3|=3.3
so the answer to the second one is |2.5|, |-3|, |3.3|, |-4|
Alan is 14 years old
He is twice as old as James
then Alan is the elder brother
Alan is twice as old means his age is double the age of James
Alans age = 2 x james age
that means James must be half of Alans age
Alans age = 14 years
James age = 14 / 2 = 7 years
therefore James is 7 years old

It doesn't. One third multiplied by three fourths is one fourth or .25
4x + 160y = 120
and
1x + 240y = 80
that will be be the equations. if we multiply the bottom equation by 4 we get:
4x + 960y = 320
now subtract one equation from another:
4x + 160y = 120
-(4x + 960y = 320)
and get:
-800y = -200
y = $0.25
now plug this into one equation
x +240(.25) = 80
x + 60 = 80
x = $20
so $20 per day and $0.25 per mile
