⦟KLJ and ⦟JLM are a linear pair. Find the measures of ⦟KLJ and ⦟JLM.
KATRIN_1 [288]

Answer:

Step-by-step explanation:

6x + 12 + 4x + 8 =  180 {Linear pair}

6x + 4x + 12 + 8 = 180 {Combine like terms}

         10x + 20  = 180   {Subtract 20 from both sides}

              10x =  180 - 20

             10x  = 160    {Divide both sides by 10}

               x = 160/10

                x = 16

m∠KLJ = 6*16 + 12

            = 96 +12

            = 108

m∠JLM = 4*16 + 8

            = 64 + 8

            = 72

A group of students is arranging squares into layers to create a project. The first layer has 5 squares. The second layer has 10
True [87]

Answer:

  • Recursive formula:

                                         a_1=5;a_n=5+a_{n-1},n>0

Explanation:

All the shown formulae in the choice list are recursive formulae instead of explicit formulae.

Explicit formulae that represent arithmetic sequences are of the form:

  • a_n=a_1+(d-1)n

That kind of formula permits to determine any term knowing the first term, the number of the term searched, and the common difference (d).

On the other hand, the recursive formulae let you to calculate one term knowing the previous term and the difference.

In this case, the difference in the number of squares of two consecutive terms is:

  • differece = number of squares in the second layer - number of squares in the first layer.

  • d = 10 - 5 = 5

Then, the recursive formula is:

  • a_1=5;a_n=5+a_{n-1},n>0
