allsm [11]3 years ago
8 0

Answer:

x = 1 and y =5

Step-by-step explanation:

8x -2y= -2\\Divide by -2\\-4x+y = 1\\add 4x\\y= 1+4x\\

Substitute this value of y in the next equation.

9x+5(1+4x) = 34\\9x+5+20x=34\\29x+5=34\\29x=29\\x=1

Solve for y using x.

y=4x+1\\y=4(1)+1\\y=5

Given: m∠1 = 140°, find m∠6.<br> A) 40° <br> B) 50° <br> C) 90° <br> D) 140°
laila [671]

Answer:

The answer is A

Step-by-step explanation:

When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.
