Answer:
Step-by-step explanation:
x = last month
y = this month
y = 2x + 7
y = 43
43 = 2x + 7
43 - 7 = 2x
36 = 2x
36/2 = x
18 = x <== he sold 18 gym memberships last month
98/2487= <span>0.0394049055</span>
So simple... 3\ll=27\100 which equals 27.0 or 0.27
<span>If the nemesis has "7/8 of her cats plus 2" it can be written like this: 7/8 x + 2 = x, where x is the number of the cats. After that we can solve the equation. x - 7/8 x = 2; 1/8 x = 2; x = 2 : 1/8 = 2 * 8 = 16. Answer: The nemesis has 16 cats.</span>
Answer:
hi
Step-by-step explanation:
the function is c(x) = 31 + 0.18*x
where $31 is a fixed cost, and $0.18 is the cost per mile drive (where the number of miles driven)
So the fixed cost, $31, is the cost per day of rent (this price does not depend on the number x), and the linear cost, $0.18, is the cost per mile driven (because this number is multiplied by x in the function), then the right answer is B: "$31 is the cost per day to rent the car and $0.18 is the cost per mile."
