Answer:
-5/8
Step-by-step explanation:
make them common denominatiers
(1/4)2 = 2/8
-7/8+2/8 = -5/8
Answer:
Ill help
Step-by-step explanation:
The answer is: x= 5/12 or x=0.416
C(m) = 0.55m+24
Alberto's millage will be the variable so for m ( number of miles) times 0.55 plus the initial $24 you should get his final cost (C(m)).
Answer:
If x = 20, then y = 12.5/20 = 0.625
Step-by-step explanation:
The pertinent relationship is y = k/x, where k is the constant of proportionality.
Subbing 5 for y and 2.5 for x yields 5 = k/2.5, so k = 12.5.
Then the specific relationship fit to this problem is y = 12.5/x.
If x = 20, then y = 12.5/20 = 0.625
