Answer:240 square feet
Step-by-step explanation:
X + y = 6
x - 6y = -9
Subtract the equations, you get:
y - (-6y) = 6 - (-9)
7y = 15
y = 15/7
x + 15/7 = 6
x + 15/7 = 42/7
x = (42-15)/7
x = 27/15
None of your answer choices are correct, since the solution to the systems of equation is (27/15, 15/7)
Answer:
≅ 0.02083333
Step-by-step explanation:

48
≅ 0.02083333
1: Conversion a decimal number to a fraction: 3.5
2: Multiple: 3.5 * 2
7
= 7 · 2
2 · 7
= 14
14
= 1 · 14
1 · 14
= 1

Answer:
76.
Step-by-step explanation:
It is given that N is a 2-digit number.
Last two digits of N^2 is the same as N.
We know that, a number is even if it ends with 0,2,4,6,8.
If 0 is in end then we get two zeros in the square of that number.
It is clear that, number should ends with 6 to get the same number at the end.
It is clear that last two digits of (76)^2 is the same as 76.
Therefore, the required number is 76.
