Answer:
A, C, and D.
Step-by-step explanation:
The other does not go through the origin, therefore it is not proportional.
Answer:
Equations::
4c + 8t = 58
2c + 3t = 23
----------------
Modify for elimination:
4c (4c*1) + 8t (8t*1)= 58
4c (2c*2) + 6t (3t*2)= 46
---------------------
Subtract and solve for "t":
2t (8t-6t) = 12
t = $6 (cost of one table)
-----
Solve for "c":
2c + 3t = 23
2c + 18 = 23
2c = 5
c = $2.50 (cost of one chair)

Answer:
-2
Step-by-step explanation:
Given:
I have 13 gallons of water and I pour 10 out.
I have about 10.6 in the container I poured it in.
To find:
The the remaining water.
Solution:
I have 13 gallons of water and I pour 10 out. So, the remaining water after this step is
Then, I have about 10.6 in the container I poured it in. So, the remaining water after this step is
Therefore, the final remaining amount of water is 13.6 gallons.
