Answer:

Step-by-step explanation:

arc BE is the same as the interior angle, or 76°

BE = 76 °

we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°

Now we know all the arcs but arc CD

so use the idea that all the way around the circle is 360°

360 = 76 + 104 + 140 + CD

360 - 76 - 104 - 140 = CD

40 = CD

CD = 40 °

Mrs Lim bought a number of plates at an average price of $6. She decided to buy another plate which cost $18. The average price

soldi70 [24.7K]

Answer: 6

Step-by-step explanation:

Let x represent the number of plates bought for $6

Let y represent the Total number of plates bought = x + 1

Remember that Mrs. Lim bought another plate for $18

Total cost ÷ Total plates = Average Cost

$\dfrac{6x+18}{x+1}=8\\$

6x + 18 = 8(x + 1)

6x + 18 = 8x + 8

18 = 2x + 8

10 = 2x

5 = x

y = x + 1

= 5 + 1

= 6
