Answer:
X= 5/12 + 1/24y
Y= -10 + 29x
Step-by-step explanation:
2(10- 24x)+ 2y 2(10- 24x)+ 2y
20 - 48x +2y 20 - 48x +2y
48x =20 +2y -2y = 20- 48x
/48 /48 /48 /-2 /-2 /-2
x= 5/12 + 1/24y y= -10 +29x
325 divided by area 21 2/3. always area divided by length
Answer:
Width of the rectangle = 10 feet
Length of the rectangle = 25 feet
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = x feet
Length of the rectangle = 3x - 5 feet
Perimeter of the rectangle = 70 feet
Perimeter of a rectangle = 2(length + width)
70 = 2{x + (3x - 5)}
70 = 2{x + 3x - 5}
70 = 2(4x - 5)
70 = 8x - 10
70 + 10 = 8x
80 = 8x
Divide both sides by 8
x = 80 / 8
= 10
Width of the rectangle = 10 feet
Length of the rectangle = 3(10) - 5
= 30 - 5
= 25 feet
8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
