Answer:
x=15
Step-by-step explanation:
x+165degrees=180degrees
x=180-165
x=15
Well then, you do
850 = 50x + 250
-250 -250
600 = 50x
/50 /50
12 = x
or
x = 12

Answer:
12 black beads
Step-by-step explanation:
Given the ration of gold beads to black beads on the short necklace:

Since the ratio of 4:1 has 5 total parts, you can take the total amount of beads in the long necklace and divide by 5:
60 ÷ 5 = 12
12 beads represents 1 part of the ratio, so that would be the number of black beads. To check, multiply 12 by 4: 12 x 4 = 48, and set up a ratio:
48: 12 = 4: 1
