Before you will sum up the following equation, first you must multiply the first equation by two and came up with 16x+14y=78 and then add it to the second equation which is 4x-14y=-68 and the remaining variable is 20x=10 then get the value of X and the value is 1/2 or 0.5. I hope you are satisfied with my answer
Answer:
7 horses and 8 chickens
Step-by-step explanation:
To solve this, first you would need to list out all of the available ratios. Then, find out how many legs are in each option.:
14 horses and 1 chicken = 58 legs
13 horses and 2 chickens = 56 legs
12 horses and 3 chickens = etc.
11 horses and 4 chickens
10 horses and 5 chickens
9 horses and 6 chickens
8 horses and 7 chickens
7 horses and 8 chickens = 44 legs!
6 horses and 9 chickens
5 horses and 10 chickens
4 horses and 11 chickens
3 horses and 12 chickens
2 horses and 13 chickens
1 horses and 14 chickens
Answer:
<u>Proportional relationship formula:</u>
- y = kx, where k is the constant of proportionality
Use one of the ordered pairs to calculate the value of k
<h3>Company A</h3>
Point (2, 20)
The equation: y = 10h
<h3>Company B</h3>
Point (3, 20)
- 20 = k*3
- k = 20/3
- The equation: y = 20/3h
Company A has greater unit rate as 10 > 20/3
