This scenario is all about creating equal groups of 4 candies. Because we know the total number of candies that were used, the 4 is a part and we are missing the other part(groups). We can think of it as how many groups of 4 will result in 76. This is shown in Choice A.
Answer: a = 30
Step-by-step explanation:
There are a total of 60 permutations makeable from those letters 3 at a time.
11
(9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99)
Those numbers divisible by 9 are the multiple of 9; thus need to know how many multiples of 9 there are between 1 and 100:
100 ÷ 9 = 11 r 1 ÷ last multiple of 9 is 11 × 9 (= 99)
→ There are 11 - 1 + 1 = 11 numbers between 1 and 100 which are divisible by 9.
(They are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.)
Answer:15
Step-by-step explanation:
x=180-(110+55)=15
