a jewelry is designing a crown. the crown must have at least 45 gems using only emeralds, rubies, and diamonds. the number of ru
bies 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>
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) <span>≥ 45 is the answer I got. The answer to that inequality would be X </span><span>≥ 7 I think.</span>
using the two angles in the triangle, 1 and 2, it can be 180- the sum of angles 1 and 2, which is c. using angle 4, it can also be 180 - the equation for angle 4
when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):
then you need to include these two possible solutions:
