Gianna paid less per necklace so she got the better deal
Gianna: 50.75 / 7 = 7.25
So she paid $7.25 per necklace
Winnie: 24.60 / 3 = 8.20
So she paid $8.20 per necklace
-3(2/5x-2)=18
multiply -3 by 2/5 and my -2
-6/5x + 6 = 18
subtract 6 from each side
-6/5x = 12
divide by -6/5, multiply 12 by -5/6
x = -10
Answer:
x=80 degree
Step-by-step explanation:
(x-5)+(x-6)+(2x-7)+x+(2x-2)=540 degree (sum of interior angles of a pentagon)
x-5+x-6+2x-7+x+2x-2=540
7x-20=540
7x=540+20
x=560/7
x=80 degree
30 + 75x= 210
Subtract 30 from both sides
75x=180
Divide both sides by 75
X =2.4
