Question

A student needs to collect at least 10 flowers for a science project. The student has already collected 3 flowers. The inequality shown can be used to find N, the number of flowers the student still needs. N + 3 > 10 (has a line underneath the greater than sign) Which inequality represents the solution set for this situation? A) N < 13 (has a line underneath the less than sign)

B) N > 13 (has a line underneath the greater than sign)
C) N < 7 (has a line underneath the less than sign)
D) N > 7 (has a line underneath the greater than sign)

Answer 1

D) n ≥ 7

Explanation:

n + 3 > 10 is given.

so to find n, the amount needed to have the total of 10,

we do: 10 - 3 = 7. (inverse operations)

7 = n, is the solution to the variable, n.

"≥" means equal to or greater than, so it is n = 7, but since the only answer choice related to this is "n ≥ 7", it is that one because it means "= and/or >," which in this case it is equal, so we choose "D."

Answer 2

The answer is D) N+3>10
N>10-3=7(when crossing the equality sign).
