Question

a jewelry is designing a crown. the crown must have at least 45 gems using only emeralds, rubies, and diamonds. the number of rubies must be 1 less than 3 times the number of emeralds. the number of diamonds must be 4 or less than the number of rubies. which inequality could the jewelry maker use to find the number of emeralds, x, that can be placed on the crown>

Answer 1

I'm horrible at this so I'm just guessing.
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.
The answer to that inequality would be
X ≥  7 I think.
