Answer:
x=-3
|-x| = 3
|x| = 3
Step-by-step explanation:
we know that
If a number is a solution of a equation, then the number must satisfy the equation
<em>Verify each case</em>
case 1) we have
x=3
substitute the value of x=-3
-3=3 -----> is not true
therefore
x=-3 is not a solution of the given equation
case 2) we have
x=-3
substitute the value of x=-3
-3=-3 -----> is true
therefore
x=-3 is a solution of the given equation
case 3) we have
|-x| = 3
substitute the value of x=-3
|-(-3)| = 3
|3| = 3
3=3-----> is true
therefore
x=-3 is a solution of the given equation
case 4) we have
|x| = 3
substitute the value of x=-3
|(-3)| = 3
3=3-----> is true
therefore
x=-3 is a solution of the given equation
case 5) we have
-|x| = 3
substitute the value of x=-3
-|(-3)| = 3
-3=3-----> is not true
therefore
x=-3 is not a solution of the given equation
First, convert 2 hours into minutes. You know that there are 60 minutes in 1 hour. Thus, 2 hours = 120 minutes.
Set a ratio to solve for x, the number of pages Tim can read in 2 hours (120 minutes). The numerator represents the number of pages read, and the denominator represents the amount of time elapsed.
Use the cross-multiplying method, where you multiply x by 120 and 48 by 100.
To isolate x, divide both sides of the equation by 120.
The answer is x = 40.
Therefore, Tim can read 40 pages in 48 minutes.
Hope this helps! :)

Answer:
20
Step-by-step explanation:
19+76+12+53+23=183$
she had 325
325-183= 140
therefor 140$- 120$ would leave Tasha with 20
The top right is the answer. The base should be square with lengths of 8 and the height is 10.
