find a number that is exactly halfway between 1 and 27

Answers

Answer:

14

Step-by-step explanation:

A number that is exactly halfway between 1 and 27 is the middle number

In other words, we want to find the median between 1 and 27

Median = (x + y) / 2

Let

x = 1

y = 27

Median = (x + y) / 2

= (1 + 27) / 2

= 28/2

= 14

Therefore, the number between 1 and 27 is 14

HELP!!! please marked brainliest

Answers

Answer:

m∠KLM = 100

Step-by-step explanation:

First, make both equal to each other

26x + 22 = 38x - 14

Subtract 26x from both sides

22 = 12x - 14

Add 14 to both sides to isolate the variable

32 = 12x

Divide both sides by 12

x = 3

----------------- To find m∠KLM take one angle:

38x - 14

Replace the x with 3

38(3) - 14

Multiply 38 by 3

114 - 14

Subtract 14 from 114

100

m∠KLM = 100
