Answer:
C
Step-by-step explanation:
Given
5x + 7 ≤ - 3 or 3x - 4 ≥ 11
Solve the inequalities either side of the or
5x + 7 ≤ - 3 ( subtract 7 from both sides )
5x ≤ - 10 ( divide both sides by 5 )
x ≤ - 2
or
3x - 4 ≥ 11 ( add 4 to both sides )
3x ≥ 15 ( divide both sides by 3 )
x ≥ 5
Solution is x ≤ - 2 or x ≥ 5 → C
x= -1 or x=3

for every 6 pairs of wedges she owns 2 Stillettos, 3 sneakers and 4 sandals
18/6 =3
3*2 =6 stilettos
3*3 = 9 sneakers
3*4 =12 sandals
18 + 6 + 9 + 12 = 45 pairs of shoes
