5-2(y+1)=21

Distribute
5-2y-2= 21

Combine like terms
3-2y=21

Subtract 3 from both sides
-2y= 18

Divide both sides by -2
y= -9

Final answer: y=-9

Since ΔABC ~ ΔEDC, ∠B = ∠D.

Since both triangles appear to be similar, the corresponding angles are the same, and corresponding sides are the same or have the same ratio.

We can write an equation to resemble the problem:

8x + 16 = 120

Solve for x.

8x + 16 = 120

~Subtract 16 to both sides

8x + 16 - 16 = 120 - 16

~Simplify

8x = 104

~Divide 8 to both sides

8x/8 = 104/8

~Simplify

x = 13

Therefore, the answer is 13.

Best of Luck!

Answer:

<em>9 sheep and 5 goats</em>

Step-by-step explanation:

s + g = 14

125s + 75g = 1500

125( 14 - g ) + 75g = 1500

1750 - 125 g + 75g = 1500

50g = 250

g = <em>5 goats</em>

s = <em>9 sheep</em>
