Answer:
Step-by-step explanation:
Two equations of planes are given.
We have to find the equation of the line which is formed by intersection of these two planes in parametric form
Let us eliminate one variable
Multiply I equation by 5 and subtract II from 5 * I
Or 
Consider II equation
5x+y-z=4
Let z=z
x = \frac{3z-16}{16} and y = \frac{31z}{16}-1
Answer:
12>x>10
Step-by-step explanation:
-25<-3x+5
-3x+5<-31

Answer:
56.35 ft^2, or 56 7/20 ft^2
Step-by-step explanation:
One way of doing this problem quickly is to convert both measurements into improper fractions before multiplying them:
9 4/5 = 49/5 and 5 3/4 = 23/4.
Then the area of the garden is 49/5 times 23/4, or 1127/20 ft^2, or
56.35 ft^2, or 56 7/20 ft^2.
