Answer:
Not equivalent
Step-by-step explanation:
Distribute the negative in the parentheses. It basically multiplying everything inside by -1.
add like terms
Not equivalent since the 6x is positive
Answer: 412
Step-by-step explanation:
We need to calculate how many different groups of 2 volunteers come out of the 17 volunteers in the Eastern division
C¹⁷₂ = 17!/ 2! (17-2)! ⇒17*16*15!/ 2! * 15! ⇒ C¹⁷₂ = 17*16/2
C¹⁷₂ = 136
And the same criteria is valid for Western division volunteers
C²⁴₂ = 24!/ 2! *(24-2)! ⇒24*23*22! / 2!*22! ⇒ C²⁴₂ = 24*23/2
C²⁴₂ = 276
And the sum of these two groups will be the total ways the officers can be selected
C = 276 + 136 = 412
For this case, the first thing we must do is to group similar terms.
We have then:
n (9 + 15) + (12-6)
Rewriting:
24n - 6 ft
Answer:
(9n + 12) ft + (15n -6) ft = 24n - 6 ft
Answer:
75 Dragons
Step-by-step explanation:
We know that the ratio is 5 dragons and 4 knights.
Now, there are 60 knights, meaning the original number of knights (4), was multiplied by 15. So, if one side is multiplied by 15, the other side must follow the same rule. So, 15 x 5 = 75.
There are 75 Dragons.
