Answer:
-76/8 = -19/2
In an arithmetic sequence, the nth term, an, is given by the formula:
an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.
So, a9 = a1 + 8d
Substituting in the given data, 12 = 88 + 8d
-76 = 8d
d = -76/8 = -19/2

rise/run
rising 20 and running 2
20/2=10
Because i<span>t's off by an order of magnitude. Should be near 27,000, not 2,700
The actual answer is </span><span>it's 26,187, to be precise.</span>
Answer:
x = 3
Step-by-step explanation:
the midsegment XW is half the sum of the parallel bases , that is
7x + 10 = (46 + 16 ) = × 62 = 31 ( subtract 10 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
