Joes age (j) is half Martha’s (m). Combined, their age is 42. What are their ages?

svp [43]

Answer:

Joe is 14.

Martha is 28.

Step-by-step explanation:

Use the variables and information from the question to make equations.

If Joe's age is half Martha's:

(1/2)m = j OR 2j = m

If their ages combined is 42:

m + j = 42

We can substitute the equation m=2j into equation m + j = 42, replacing "m".

m + j = 42 Substitute m for 2j

2j + j = 42 Combine like terms, terms with same varables

3j = 42 Divide both sides by 3 to isolate j

j = 14 Joe's age

Since j = 14, we can substitute it into equation m=2j to find "m".

m = 2j Substitute j for 14

m = 2(14) Simplify

m = 28 Martha's age

Therefore Joe is 14 and Martha is 28.

Given that LON is a right angle, find the measure of x.

sveta [45]

Answer:

$x=30\°$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LOM+m∠MON=m∠LON ----> by angle addition postulate

we have

m∠LOM=2x°

m∠MON=x°

m∠LON=90° ----> is a right angle

substitute the values

$2x+x=90$

solve for x

$3x=90$

$x=30\°$
