To find the number of perfume bottles that are made of crystal, multiply 99 by 2/3.
An easy way to do this in your head is to divide 99 by 3, and then multiply it by 2.
99/3=33
33*2=66
66 bottles in Tiffany's collection are made of crystal.
167<6+7(2-7r)167<6+14-49r
167-6-14<-48r
147<-49 r
r >-3
Explanation:
x+91 and x+111 are supplementary angles (they add up to 180), so you would set an equation by adding both of them to equal 180:
x + 91 + x + 111 = 180
add like terms
2x + 202 = 180
subtract 202 from both sides
2x = -22
divide both sides by 2 to get the answer:
x = -11
