Answer:
I. x + y = -3 --> y = -x - 3
II. y = 2x
2x = -x - 3
3x = - 3
x = -1
y = 2*(-1) = -2
The range of the set is 17 because the range is the largest number minus the smallest number in this set 93 is the largest and 76 is the smallest therefore you subtract them 93-76=17.
9 * 20 will be 180 ft^2 so 180 is your answer

Answer:
Step-by-step explanation:
According to the given statement two pieces are of same length:
If the length of one piece is x,
Then the length of other piece is also x.
And one piece is 2 feet longer than the other two = x+2
Total length of a board = 10 foot
Now make the equation from these terms:
x+x+x+2= 10
This is the equation of the given question.
You can further solve this equation:
x+x+x+2=10
3x+2=10
Now combine the constants:
3x=10-2
3x=8
x=8/3
x=2.67
It means that the length of two pieces of same length is 2.67
And the length of one piece which is longer than the other two = x+2 = 2.67+2 = 4.67 ....
