Answer: The required equation is 
Maria can cut 6 sections from the remaining rope.
Step-by-step explanation:
The total length of rope = 7 feet
since 1 feet = 12 inches
Therefore, 7 feet=
Let x be the number of sections.
Since the instructions are to use 34.5 inches of rope to tie a tarp on top the the tent. Then, the remaining rope should be cut 8 1/4 inch sections to tie tent to stakes in the ground.
then the required equation will be

So, maria can cut 6 sections.
Answer:

Step-by-step explanation:
The angles add up to 90 degrees.
x + 2x + x + 10 = 90
Combine like terms.
4x + 10 = 90
Subtract 10 from both sides.
4x = 80
Divide both sides by 4.
x = 20
