Answer:
x = 8
Step-by-step explanation:
Equilateral triangle : congruent angles
3(7x+4) = 180
21x + 12 = 180
21x = 180-12
x = 168/21
x = 8
4|x - 1| - 7 = -3 |add 7 to both sides
4|x - 1| = 4 |divide both sides by 4
|x - 1| = 1 ⇔ x - 1 = 1 or x - 1 = -1 |add 1 to both sides
x = 2 or x = 0
Answer: B.
1/2×4=4/8
1/8=1/8
1/4×2=2/8
so 4/8+2/8=6/8
and 6/8+1/8=7/8
so 7/8 ribbons will be collected
