Answer:
The answer is C
Step-by-step explanation:
Let X and Y be two proportional quantities and let K be constant.
Y=KX so Y/X=K
So for Equation number 1 we have 4y=3x and we will fill it in for 4/3=K
solving to get 1.33...
Now repeat this for the rest to complete the chart
1- 1.33...
2. 1.6
3- 1.33...
4- 0.625
Now we can see that 1 and 3 are the same, so that's how you get your answer, hope this helps!
Answer:
7x + 2y = 24 8x + 2y = 30. Subtract -x = -6 x = 6. Substitute x = 6 into 7x + 2y = 24 7(6)+ 2y = 24 42 + 2y = 24 2y = 24 - 42 2y = -18 y = -9 {6,-9} ...

Answer:
The sides are
6
inches,
8
inches and
10
inches
Explanation:
I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'
In this case the question can be answered. If
x
is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4
x+3/4x+3/4x+4=24
10/4x=20
x=8
Then the shortest side is 6and the longest side is 10
