Question

The sum of two numbers is 47. The greater number is 9 more than the smaller number. Which equation can be used to solve for the smaller number? (5 points)

Select one:
a. x + (x + 9) = 47
b. x − (x + 9) = 47
c. x(x + 9) = 47
d. x(x − 9) = 47

Answer 1

if we let "n" be "the smaller number"

how can we write "the greater number is 9 more than the smaller number"?

Answer 2

"9 more" implies we are adding 9 to the smaller number

so greater number is "n + 9"

Answer 3

"sum of two numbers is 47."

therefore smaller number + greater number = 49

therefore

n + (n+9) = 49

Answer 4

now, looking at the answer choices, they use the variable x instead of n (whoops) so simply change the variable from n to x
