Variable c is 5 more than variable a to change that into "math" you can think of "is" as meaning = so we can change "Variable c is" to c = now for the rest: : 5 more than variable a to figure this out, do you know what 5 more than 1 is ?
Is it D?
do you know what 5 more than 1 is ?
and 5 more than 2 is 7 how do you get 7 from 5 and 2. what do you do?
the idea is to learn these tricks on how to translate the English to math.
you know 5 more than 1 is 6 but how did you get 6?
and how do you write 5 added to 1 ?
5 + 1
now we use letters, but the same idea 5 more than a
in which case you get c= 5+a for the first equation it looks like the only choice with that equation is D we don't have to check the other equation, but it would be helpful (may as learn how to do this)
Variable c is also 3 less than variable a. to get the idea, I would first use a number for "a" 3 less than 4 is 1 3 less than 5 is 2 so it looks like we are doing 4-3 or 5-3 or using "a" a-3
and the 2nd equation is c= a-3 which again is choice D
I already knew that I just wanted someone else's opinion. Thanks either way. :]
