From the reference made in the task, we can assume that 1/2 of the costume material is used for trimming. Given that she employs 48 yard of material, we hav divide this by 2 and get how many yards she has used for trimming.
The syncline is actually part of the younger layers
The anticline would be the oldest layer at the fold
Answer:
x=-16/3 and y =47/6
Explanation:
Subtract the 2 equations to eliminate the variable y
2x+2y=5
-(5x+2y=-11)
---------------
-3x=16
Divide by -3 on both sides
x= -16/3
Plug -16/3 in for x in the first equation to find y
2x+2y=5
2(-16/3)+2y=5
Multiply
-32/3+2y=5
Add 32/3 to both sides
2y=47/3
Divide both sides by 2
y=47/6
x=-16/3 and y =47/6
Hope this helps! :)
