60= n/3 + 52
-52. -52
8= n/3
You then take 3/1 times 8 therefore you leave n by itself
n = 24
Answer:
= 1+2n and 63
Step-by-step explanation:
the question belongs to arithmetic sequence and
can be determined by the formula
= a1 + d (n-1)
Let "
" represents the number of band members in the nth row
and 'd' represents the common difference.( as stated each row has 2 more band members than the row before it)
therefore, d=2
'a1' represents first row that has three members. So, a1 = 3
->Rule for nth term will be:
= 3 + 2(n-1)
= 3 + 2n -2
= 1+2n
-> In order to find total number of band members '
'
Let
represent total number in n rows
We'll use the formula, i.e
= n/1 (
+
)
where, n is the number of terms,
is the first term and
is the last term
So,
n=7
= 1 + 2(7)= 15
=>
= 7/2 (3 + 15)
= 63
The total number of band members are 63
Answer:
D
Step-by-step explanation:
These I's are being used as sticks
lets say i have 40 sticks then i add 55 more sticks to them
IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII + IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII If i were to reverse the sequence and use the 55 sticks and add 44 sticks to them it would be the same as me having 44 sticks and adding 55 more.
Answer:
-6.5
Step-by-step explanation:
-2(p - 1) = 15
-2p + 2 = 15
-2p = 13
p = -6.5
Step-by-step explanation: Using the equation, y = mx + b, the slope-intercept form, plug in the values you have and solve for b. (m is the slope.) You have y = -8 and x = 4 and m = 1/2.
