North divided by Total (Total of North, South, Central, East, and West)
North = 1
South = 4
Central = 2
East = 3
West = 2
North ÷ Total
1 ÷ (1 + 4 + 2 + 3 + 2 )
1 ÷ (12)
= 
Answer: B
Divide both sides of the equation by the same term
7/100=100z/100
Simplify
Cancel the terms that are in both The numerator and the denominator
Move the variable to the left
Z=7/100
Answer:
- Part 2 - ∠EGF = 105°
- Part 3 - ∠D = 65
<h3>________________________________________________</h3>
Step-by-step explanation for Part-2:
<u>We know that:</u>
- ∠EFG = 32°
- ∠AEG = 137°
- ∠EFG + ∠FGE + ∠GEF = 180°
<u>Work:</u>
- ∠EFG + ∠FGE + ∠GEF = 180°
- 32 + ∠FGE + (180 - 137) = 180°
- => 32 + ∠FGE + 43 = 180°
- => 75 + ∠FGE = 180°
- => ∠FGE = 180 - 75
- => ∠FGE = ∠EGF = 105°
Hence, the measure of ∠EGF is 105°.

Step-by-step explanation for Part-3:
<u>We know that:</u>
- CD = CA
- This triangle is an isosceles triangle.
- ∠D = ∠A
<u>Work:</u>
- 50 + ∠D + ∠A = 180
- => ∠D + ∠D = 130
- => 2∠D = 130
- => ∠D = 130/2
- => ∠D = 65
Hence, the measure of ∠D is 65°

Let initially number of fishes =x
He gives 2/3 of his fish to a local high school, that is he gives 2x/3 fish .
So number of fishes left = x -(2x/3) = x/3 . And he gives 2/5 of x/3 to an elementary school , that is , he gives 2x/15 fishes to the elementary school. And finally the number of fishes left =30 , that is
So initially he have 150 fishes .
