Answer:
1 Cubic yard is equal to 27 cubic feet. To convert cubic yards to cubic feet, multiply the cubic yard value by 27. For example, to convert 2 cubic yards to cubic feet, multiply 2 by 27, that makes 54 cu ft is 2 cu yd.
I’m sorry bc I don’t know how to solve all of them but
#5 is C
#3, the equation is y=4
#4, the equation is x=-6
The answer would be -7/10
