Answer:
-1.362637
or if you round your answer -1.36
Step-by-step explanation:
solve for k by simplifying both sides of the equation and isolating the variable.
Answer:
x = 4.1
Step-by-step explanation:
6x-3 + 3x+6 + 5x = 60
14x + 3 = 60
14x = 60 - 3
14x = 57
x = 57/14
x = 4.1
Answer:
32
Step-by-step explanation:
Divide 24 by 3/4 to find the number.
24 ÷ 3/4
= 24 × 4/3
= 32
Answer:
13
Step-by-step explanation:
Put n as 4

Hope this helps :)
Notice how Pattern 2 is Pattern 1 with 4 balls added in the bottom row.
Pattern 3 is Pattern 2 with 5 more balls.
Pattern 4 is Pattern 3 with 6 more balls.
Generalizing the trend, we expect Pattern
to be identical to Pattern
with
more balls.
If
is the number of balls in the
-th pattern, then we have the recursive relation

We can solve this recurrence by substitution. Using the definition of
, we have


and so on, down to

Recall that

Then we find
