Answer:
x = 15
Step-by-step explanation:
8x + 9 and 51 are same- side interior angles and sum to 180° , then
8x + 9 + 51 = 180
8x + 60 = 180 ( subtract 60 from both sides )
8x = 120 ( divide both sides by 8 )
x = 15
Jayleen ordered more fabric by 5 centimeters...
Bria ordered 145 cm and Jayleen had 1.5 m ( 150 cm )
So 145<150
Therefore Jayleen ordered more than Bria.
