here is a contradiction because in one inequality x can be equal to 15 ; and in the other it cannot
Answer:
x=20
Step-by-step explanation:
x=20 because 4×20=80
and 80-20= 60
Decimal form: 18.8
Mixed number: -18 4/5
Exact form: -94/5

and surely you know how much that is.
Answer:

Step-by-step explanation:
We are given an expression to solve for the displacement (x), so in order to find velocity (v), we need to differentiate the function.
============================================================
Solving :
⇒ 
⇒ 
⇒ 
⇒ 
Using this equation, we can find the velocity if a value of t is given.
