an old book listed that $72$ turkeys were bought for $\$\square.\square\square$ each, at a total cost of $\$\square 67.9\square.
Westkost [7]

The cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94

<h3>Cost of each turkey</h3><h3 />
  • Total number of turkey bought = 72
  • Total cost = $67.9

Cost of each turkey = Total cost / Total number of turkey bought

= 67.9 / 72

= 0.943055555555555

Approximately,

Cost of each turkey = $0.94

Therefore, the cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94

MZRSK = x + 53, m KST = x + 109,<br> and mZRST = 156º<br><br><br> Find x.
Dahasolnce [82]

Answer:

-3 = x

Step-by-step explanation:

Since we are not given a midpoint, we use the Angle Addition Postulate:

156 = [x + 109] + [x + 53]

156 = 162 + 2x

-162 - 162

_______________

−6 = 2x

___ ___

2 2

−3 = x

[−3 + 53] + [−3 + 109] = 156

50 106

156 = 156 ☑

Therefore, -3 = xis a genuine statement.

I am joyous to assist you anytime.
