Step-by-step explanation:
J = 2b
M = J + 7
M = 21
J = 21 - 7
J = 14
B = 7
<em>Equation:</em>
If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.
Make use of prime factorizations:

Both terms have a common factor of
:

- - -
The second one is not true! We can write

Both terms have a common factor of
:

Since
, and
, we'd still have to show that
is a multiple of 6. This is impossible, because
and there is no multiple of 2 that can be factored out.
Answer: 30 degrees
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The easiest way to solve this would be to find the difference between the numbers. We can do
to find the difference of
. We can then make sure this is true for the rest of the sequence by adding 6 to each number.




Now that we've verified that this is true, we know the answer is C
