All you have to do is to multiply 35m and -30n by 0.4, one by one, to produce two terms separated by a " _ " symbol.
Answer:
3003
Step-by-step explanation:
The number of differents menus containing 10 main courses that the restaurant can make if it has 15 main courses from which to chose is calculated through the combination: 15C10. The formula of the combination is: nCr = n! / ((r!) x(n - r)!)
Where r=10 and n=15
Substituting the values to the equation: 15C10 = 15! / (10!)x(10 - 5)! = 3003
Then there are 3003 different menus that a restaurant can makeif it has 15 main courses from which to choose.
Answer:
B
Step-by-step explanation:
Simplify the numerator and denominator of the fraction, that is
- 
Multiply the numerator/denominator of the first fraction by y
Multiply the numerator/denominator of the second fraction by x
- 
= 
Similarly
+ 
Multiply numerator/denominator of the first fraction by x
Multiply numerator/denominator of second fraction by y
+ 
= 
To perform the division
leave the fraction on the numerator
Change division to multiplication
Turn the fraction on the denominator upside down, thus
× 
Cancel xy on the numerator and denominator
= 
← factor 2 out of each term on the numerator
= 
→ B
Yes, all number sets are a real number
