Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.

katovenus [111]

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>

Determine whether this system of equations has one solution, no solution, or infinitely many solutions.
prohojiy [21]

Answer:

The only solution I see is for x=0

Step-by-step explanation:

y=8x+2

y=-8x+2

y=y so substitute:

8X+2=-8X+2

Subtract 2 from each side

8X=-8X

divide each side by 8

x=-x

The only solution I see is for x=0

monitta

Answer:

z =  \frac{47}{7} = 6 \frac{5}{7}

Step-by-step explanation:

7 =  \frac{40}{z - 1}  \\ 7(z - 1) = 40 \\ 7z - 7 = 40 \\ 7z = 40 + 7 \\ 7z = 47 \\
