-2m-9 is the simplified expression
-4.2c+4.8d is the answer to this equation.
Answer:
Consider the following calculations
Step-by-step explanation:
Since 1 Blimp uses 2 components of B and C each
=> choosing 2 components of B(remaining after using in other prototypes) for 1st model= 22C2
choosing 2 components of B(remaining after using in other prototypes) for 2nd model= 21C2
choosing 2 components of B(remaining after using in other prototypes) for 3rd model= 20C2
choosing 2 components of B(remaining after using in other prototypes) for 4th model= 19C2
choosing 2 components of B(remaining after using in other prototypes) for 5th model= 18C2
and choosing 2 components of C(remaining after using in other prototypes) = 24C2
Similarly for C
P(5 prototypes of Blimp created)=[(22C2 / 25C2 )*(24C2 / 25C2 )] + [(21C2 / 25C2 )*(23C2 / 25C2 )]+[(20C2 / 25C2 )*(22C2 / 25C2 )]+[(19C2 / 25C2 )*(21C2 / 25C2 )]+[(18C2 / 25C2 )*(20C2 / 25C2 )]
Answer:
equation:x*1/5=9/20
answer=9/4
Step-by-step explanation:
9/20÷1/5=9/20×5/1 in word form you multiply 9/20 by its reciprocal.
first you want to simplify and change 9/20 to 9/4 and change 5/1 to 1/1 and then multiply to get 9/4
Answer:
60
Step-by-step explanation:
7×10=70
70-10=60
60 > 38
