Answer: They are 59 members in the band
Step-by-step explanation:
given data:
when lined up in 3 = 2 left.
when lined up in 4 = 3 left
when they are lined up in 5 = 4 left
when they are lined up in 6 = 5 left
Solution:
From the given data, we know the band number ends with 9, so we start with 9,29,49,59. We test till we arrive at our desired answer.
59/3 = 19 R 2.
59/4 = 14 R 3.
59/5 = 11 R 4.
59/6 = 9 R 5.
They are 59 members in the band.
Answer:
D.
Step-by-step explanation:
Well there are 3 2's so 3 / 6 = 1/2
It's represented by a dot.
Answer:
f(4) = 22
Step-by-step explanation:
I think that you type wrongly.
we have f(1) = -5
and f(n) = f(n-1) + 9
Find f(4)
Then
with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4
with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13
and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22
So f(4) = 22
Hope you understand.
Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
