Answer:
Step-by-step explanation:
Intersecting lines make equal opposite angles
2x + y = 50 - y
2x = 50 - 2y
x = 25 - y
A straight line represents 180°
4x + 6y + 2x + y + 2x + 3y = 180
8x + 10y = 180
8(25 - y) + 10y = 180
200 - 8y + 10y = 180
2y = -20
y = -10
x = 25 - (-10)
x = 35
Then there would be 9 girls and 23 boys
Answer:
Step-by-step explanation:
J and K are equal
8x - 23 = 6x + 11 Add 23 to both sides
8x = 6x + 11 + 23 Combine the right
8x = 6x + 34 Subtract 6x from both sides
8x - 6x = 34 Combine the left
2x = 34 Divide by 2
x = 34/2
x = 17
=================================
M and L are both supplementary to J and K respectively.
J = 8x - 23
J = 8*17 - 23
J = 136-23
J = 113
K = 113
===================================
M + 113 = 180
M = 180 - 113
M = 67
L = 67
