six times a number translates to what?
OpenStudy (anonymous):
that's the question
jimthompson5910 (jim_thompson5910):
well let's say x was some unknown number, then "six times a number" would be
6 times x = 6 * x = 6x
jimthompson5910 (jim_thompson5910):
see how I'm getting this?
OpenStudy (anonymous):
ok,it also says to translate the phrase into a mathematical expression and then simplify

jimthompson5910 (jim_thompson5910):
so what does "twice the same number" translate to
OpenStudy (anonymous):
6 times 2 would be 12
jimthompson5910 (jim_thompson5910):
well at the moment, the number is unknown
jimthompson5910 (jim_thompson5910):
so let's call it x
jimthompson5910 (jim_thompson5910):
"twice the same number" would be 2*x or just 2x

six times a number ---> 6x
twice the same number ----> 2x
OpenStudy (anonymous):
yes i see, so with your numbers it would be 6x-2x
jimthompson5910 (jim_thompson5910):
yes and that simplifies to what
OpenStudy (anonymous):
4x
jimthompson5910 (jim_thompson5910):
perfect

six times a number decreased by twice the same number
translates to 6x - 2x
that simplifies to 4x
OpenStudy (anonymous):
it would be negative right
jimthompson5910 (jim_thompson5910):
no it's 4x
jimthompson5910 (jim_thompson5910):
not -4x
OpenStudy (anonymous):
ok
