Question

mary is 64 inches tall. this is 20 inches less than twice raul's height what is rault's height

 

Answer 1

OK, Mary is 64 inches. It is 24 inches less than 84. And 84 is twice Raul's height. So Raul is 84/2 = 42

 

Does it make sense?

Answer 2

Look at it word per word, let me show you:

 

Mary is 64 inches tall. this is 20 inches less than twice raul's height what is rault's height

 

M     =  64.                M   =  20           <           2*     R.                           R =   ?

 

 

So writing that clearly, you'll get:

M = 64

 

M = 20 < 2R  or that also means M = 2R - 20

 

R = ?

Solution:

 

Just substitute the M = 64 to the M = 2R - 20

 

64 = 2R - 20

 

2R = 84

 

R = 42 in
