We have to calculate the length of a side ( x ) of the rectangle. We know the perimeter of the rectangle: P = 24 ft. Formula for the perimeter of the rectangle is: P = 2 L + 2 W. The width W = 4 ft. So: 24 = 2 * x + 2 * 4; 24 = 2 * x + 8; 2 * x = 24 - 8; 2 * x = 16; x = 16 : 2; x = 8. Answer: The length of side of a rectangle is 8 feet<span>.</span>
5x - 5y = 10
x - y = 2 . . . (1)
3x - 2y = 2 . . . (2)
(1) x 3 => 3x - 3y = 6 . . . (3)
(2) - (3) => y = -4
From (1), x - (-4) = 2
x = 2 - 4 = -2
Solution is (-2, -4)
Answer:
x < 5
Step-by-step explanation:
3x < 15
divide by 3 on both sides
x < 5
