Hello from MrBillDoesMath!
Answer:
12a + 18b
Discussion:
The question asks us to calculate
24a + 10 b - (12a - 8b) => (combine common terms)
(24a - 12a) + ( 10b + 8b) => ( as - (-8b) = + 8b)
12a + 18b

Answer:
y= -4/3 + 22
Step-by-step explanation:
y= -4/3x -1
14 = -4/3 (6) + b
14= -8 + b
22= b
I suppose that the expression you wanted to write is

. If so, then we have:
Answer:
The answer is C(x) = 60x + 14 and the answer to the second one is 7 days.
Step-by-step explanation:
C(x) =60x + 14
434 = 60x + 14
-14 -14
420 = 60x
/60 /60
7 = x
or
x = 7 days
