Answer:
L = 52°
J = 45°
K = 83°
Step-by-step explanation:
J = L - 7
K = 2L - 21
J + K + L = 180°
∴ (L - 7) + (2L - 21) + L = 180
4L - 28 = 180
4L = 208
L = 52°
J = 52 - 7 = 45°
K = 2 x 52 - 21 = 83°
Answer:
x = 4
Step-by-step explanation:
12x + 5 = 4x + 37, first subtract both sides by 5 and subtract both sides by 4x
8x = 32, next divide 8 from both sides
x = 4
The total cost including tax would be $110, you would multiply the 100 by .10 to get your tax then add it to the 100.
Answer:
The recursive formula is aₙ=aₙ₋₁ -12
Step-by-step explanation:
Recursion is a process in which each step of a pattern depends on the step or the previous steps. So a recursive sequence is a sequence where terms are defined using one or more previous terms that are given.
So a recursive formula allows you to find any term in an arithmetic sequence using a function of the previous term, where each term is the sum of the previous term and the common difference.
So, in this case you can see the common difference of all the terms by doing the following calculations between a term and its previous value:
-13-(-1)=-13+1=-12
-25-(-13)=-25+13=-12
-37-(-25)=-37+25=-12
The common difference is -12
So, <u><em>the recursive formula is aₙ=aₙ₋₁ -12 where each term is the same
to the previous term minus 12.</em></u>
The answer is 21. Hope this helped.
