Answer:
I would say false not sure though .
Step-by-step explanation:
Find the differences:
3-0 = 3
9-3 = 6
18-9 = 9
The differences increase by the previous difference plus 3
So 5 kids would have 9+3 = 12 + 18 = 30 interactions.
6 kids: 30-18 = 12 +3 = 15 + 30 = 45 interactions.
7 kids: 15+3 = 18 + 45 = 63 interactions.
8 kids: 18 +3 = 21 + 63 = 84 interactions.
9 kids: 21+3 = 24 + 84 = 108 interactions.
The answer is d. 108
Answer:
answer is .A
Step-by-step explanation:
Answer: There are 97 nickels and 108 quarters.
Step-by-step explanation:
Let x = Number of nickels, y = Number of quarters.
As per given,
x+y = 205 ...(i)
0.05x+0.25y = 31.85 ... (ii) [1 nickel = $0.05, 1 quarter = $ 0.25]
Multiply (ii) by 20, we get
x+5y=637 ...(iii)
Eliminate (i) from (iii)
4y = 432
⇒ y = 108 [Divide both sides by 4]
Put value of y in (i), we get

Hence, there are 97 nickels and 108 quarters.
