Answer:
1/3
Step-by-step explanation:
If Mackenzie drinks 8 ounces of water per 24 hours, that could be written as a ratio and a fraction. 8:24, 8/24
8/24 in its simplest form is 1/3.
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.
Answer:
Step-by-step explanation:
we know that
To find out the scale factor divide the corresponding dimensions of the model by the corresponding dimensions of the actual
so
simplify
That means
1 inch in the model represent 9 feet in the actual
Answer:
(5 , 0)
Step-by-step explanation:
7 * (−9y+4x−20)=0
9 * (−7y+16x−80)=0
-63y + 28x -140 = 0 ......a
-63y + 144x -720 = 0 .....b
b-a: 116x - 580 = 0
116x = 580
x = 5
y = (4x-20)/-9 = 0/-9 = 0
