For this case we have to write the equation of the position of each one.
We have then:
For the robber:
For the marshall
:
By the time the marshall reaches the robber we have:
From here, we clear the time.
We have then:
Answer:
it takes the marshall to catch up to the robber about 2.7 hours.
Rewrite all 4 numbers as decimals to compare them:
88/25 = 3.52
3 11/20 = 3.55
Now arrange them in the correct order:
88/25, 3 11/20, 3.551, 3.88
Hello!
Let's solve this equation for y first.
-10x+y=4
Add 10x to both side.
y=10x+4
Now, let's plug in our x-values to find y.
x: -2, -1, 0, 1, 2
y:-16,-6, 4,14,24
I hope this helps!
The way to write this expression in mathematics is A'∩B
<h3>How to solve for the expression</h3>
In order to get the right way to write this expression we have to break it down in two parts.
First we are told that some of the elements are not in A.
This is represented as A'.
Then we are told that they are in the set B. Hence we have it written as B.
Then the expression not in set A but are in set B would be written as
A'∩B.

Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
