You would have to find the y intercepts.
X + Y = 20
Substitute 0 for y then your answer would be 20 for x.
Substitute 0 for x then your answer would be 20 for y.

ANSWER

EXPLANATION
To find the average weight per bushel, we add all the three weight and divide by 3.

We convert all the mixed numbers to improper fraction to obtain,

The least common denominator for the fractions in the numerator is 8.
This implies that,

This simplifies to

This gives us,

The perimeter is just the sum of the measures of the three sides. Add 'em up. You don't have a value for x, so you will have to leave your answer in terms of x.

If length = x then width = x - 7
area = x(x -7) = 120
x^2 - 7x - 120 = 0
(x +8(x-15) = 0
x = -8 and 15
length must be positive so length = 15 ins
width = 15-7 = 8 ins
