<span><span>A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled.
So the answer would be C
But lets see the proof:
The first x and y ratio is 2:6 which equals 1:3
The second one is 4:12 which equals 1:3
The third one is 6: 18 which equals 1:3
The fourth one is 8: 24 which equals 1:3
Which means all 4 of the ratios are the same. So therefore the answer is C

Answer:
Step-by-step explanation:
x = 3y
x + y = 180°
3y + y = 180° ⇒ y = <em>45° = a</em>
x = 3( 45° ) ⇒ x = <em>135° = b</em>
Answer:
of cement
Step-by-step explanation:
since 4*6 is 24
You want to take 24 and subtract 1/4 of the rectangles area.
1/4 of 24 is 6
24 - 6 is 18

Answer:
Step-by-step explanation:
The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/ But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length, knowing that.. we can set the two expression equal to each other
3x - 10 = 2x
now solve for x
3x - 10 -2x = 2x - 2x ( subtracting 2x from both sides )
3x - 2x - 10 = 0
x - 10 = 0
x - 10 + 10 = 0 + 10
x = 10 ( yay)
