Please help me solve question 2
sergiy2304 [10]

Answer:

solution: ( 3 , 6 )

\sf y =6

\sf x =3

Step-by-step explanation:

\sf y = \frac{2}{3} x+4

\sf 2x+3y = 24

make y the subject in equation 2:

\sf 2x+3y = 24

\sf 3y = 24-2x

\sf y = \frac{24-2x}{3}

insert this in equation 1:

\sf \frac{24-2x}{3} =\frac{2}{3} x+4

\sf \sf \frac{24-2x}{3} =\frac{2x+12}{3}

\sf (24-2x) = (2x+12)

\sf -2x-2x=12-24

\sf -4x=-12

\sf x =3

solve for y:

\sf y = \frac{24-2x}{3}

\sf y = \frac{24-2(3)}{3}

\sf y =6

Find each missing angle of the trapezoid
zimovet [89]

Answer:

∠J = 107°

∠K =107°

∠L = 73°

∠M = 73°

Step-by-step explanation:

Angle J + angle M = 180°

(10x - 33) + (4x+17) = 180

simplify:

14x -16 = 180

14x = 196

x = 14

∠J = 10(14) - 33 = 107°

∠M = 4(14) + 17 = 73°
