In triangle LMN, the measure of m_L =75°and m_M is one-half m_N. what is m_M?

Answers

Answer 1

Answer: Let m(<N) be x;
We have m(<M) = 1.5x;
We solve the equation: 75 + x + 1.5x = 180;
75 + 2.5x = 180;
2.5x = 105;
x = 105 ÷ 2.5;
x = 42;
Finally, m(<M) = 63 degrees;

(dads age : ? when cindys age :18 yrs old)
A) write an equation that relates cindys age to her dads age .
B)determine if 42 is a solution to the equation. Show
your work.
C) explain the meaning of your answer in part B.

Answers

so dad=28
cindy=2
so 28-2=diffirance in age=26

A. dad-26=cindy
cindy=dad-26
dad=cindy+26
so since cindy=18
dad=18+26=44

B. if dad =42=cindy+26 so
42=x+26
subtract 26 from both sides
16=x
cindy =16 if dad =42

C. so the number of years apart they will be will always be 26 (until one of them dies)

How many rows of 6 are in 30

Answers

The answer to this question is there are 5 rows in 30 because 6x5=30 so it would be 5 ROWS. How you get that is you add 6 5 times and then you will get thirty if you do not know your multiplication that is another way of doing it.

$6 * 5 = 30 or 5 * 6 = 30$ There are 5 rows of 6 in 30 the way I got that was by counting by 6's 5 times
