Answer:
I. C = 266 textbooks.
II. S = 207 textbooks.
Step-by-step explanation:
Let the chemistry textbook be C.
Let the sociology textbook be S.
Translating the word problem into an algebraic expression, we have;
C + S = 473 ..... equation 1
S = C - 59 ..... equation 2
Substituting eqn 2 into eqn 1, we have;
C + C - 59 = 473
2C - 59 = 473
2C = 473 + 59
2C = 532
C = 532/2
C = 266 textbooks.
Next, we would determine the value of S;
S = C - 59
S = 266 - 59
S = 207 textbooks.
Check:
C + S = 473
266 + 207 = 473
473 = 473
(48 gallons) / (14 days) = 3.428571429 gallons/day = 3.43 gallons/day
Answer: 3.43 gallons/day
The only restriction on the domain is that division by zero is undefined, or "not allowed", so x cannot equal zero.
So the domain is x=(-oo,0),(0,+oo)
I’m sorry if I’m wrong but 4/36=7/8?
