Answer:

the two numbers are 19 and 32

Step-by-step explanation:

<em>let's call the numbers x and y.</em>

<em>write out the equations</em>

x + y = 51

x - y = 13

<em>simplify the second equation</em>

x = 13 + y

<em>substitute into the first equation and simplify</em>

(13 + y) + y = 51

13 + 2y = 51

2y = 51 - 13

2y = 38

y = 19

<em>substitute y for 19 in the second equation</em>

x = 13 + y

x = 13 + 19

x = 32

Consider the first four terms of an arithmetic sequence below.
VMariaS [17]
7, 13, 19 and 25 have a common difference:  6.  
6 added to 7 gives us 13; 6 added to 13 gives us 19, and so on.

Explicit formula:  a(n) = 7 + 6(n-1), where 7 is the first term and n is the counter (1, 2, 3, ...).

The first term is 7 (given).  This corresponds to n=1.

The second term is a(2) = 7 + 6(2-1), or 7 + 6, or 13.  This corresponds to n = 2.

and so on.

Answer:

144

Step-by-step explanation:

angle A + angle B = 180 (supplementary angle)

A = 4B

4b+b=180

5b=180

Divide 5 on both sides to get b=36

180-36= measure of angle A

180-36=144
