m< 6 = m< 7 (vertical angles)
11x + 8 = 12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = 11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
m<4 = 40Step-by-step explanation:
3< x< 5
step-by-step explanation:
|x - 4| < 1
there are two solutions, one positive and one negative. remember to flip the inequality when taking the negative solution
x-4 < 1 x-4 > -1
add 4 to each side
x-4+4 < 1+4 x-4+4 > -1+4
x< 5 x> 3
