Answer:
x= -63 y= -117
Step-by-step explanation:
72+10(2x+9)=36
72+20x+90=36
162+20x=36
20x=-126
×= -63
y= 2(-63)+9
y=-126+9
y= -117
The piece of ribbon would be 75 inches. The ribbon would be 75 inches because 1 foot would be 12 inches and you would multiply 12 by 6 to get 72. Then, 1/4 of a foot would be 3 inches because you could divide 12 and 4(the denominator you are dealing with) to get 3. Then, add 72 + 3 to get 75. Hope this helps!
