Answer:
141 5/7
Step-by-step explanation:
8c + 10b ÷ 7a
Let c = 7, b = 12, and a = 5
8*7 + 10*12 ÷ 7*5
Multiply and divide from left to right
56+120 ÷7*5
56+ 600/7
Get a common denominator
392/7 + 600/7
992/7
Change from an improper fraction to a mixed number
141 5/7
Step-by-step explanation:
Given figure is of HEXAGON.
the sum of the measures of the interior angles of a hexagon

Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
x ×
= 9
( divide both sides by
)
x = 9
Answer:
Required rule for
is
.
Step-by-step explanation:
Given that,

From the question: we have to write the
term of Arithmetic sequence.
Arithmetic Sequence or Arithmetic progression (A.P) : It is a sequence which possess that difference between of two successive sequence is always constant.

where,
is the first term of A.P
is the common difference.
is the last term or general term.
The above sequence to be in A.P then their common difference should be equal.

Now, Formula of General Term is 
So, 
Substituting the value of
we get,

Then General term (
) of given data is

Therefore, Required rule for
is
.
