Answer:

Step-by-step explanation:
Let the original fraction be 
Then adding 1 to the numerator gives
=
( cross- multiply )
⇒ y = 5x + 5 → (1)
Subtracting 1 from the denominator gives
=
(cross- multiply )
y - 1 = 7x → (2)
Substitute y = 5x + 5 into (2)
5x + 5 - 1 = 7x ← subtract 5x from both sides
4 = 2x ⇒ x = 2
Substitute x = 2 into (1)
y = (5 × 2) + 5 = 10 + 5 = 15
Hence original fraction = 
I would do 120 - 45. Now that she has 75 left I would do 75 - 15 * 3 Since 45 Is all that she has left.
If I were you choose a variable I would say h for hours. And h is equal to 3.
In result the whole equation would be 120 - 45 - 15 * h but since h is equal to 3 , We can write it as 120 - 45 - 15 * 3. Leaving Audrey with $30 left.
Correct me if I am wrong :)
y = -3.7x + 1 when x = -2
Plug in:
y = -3.7(-2) + 1
-3.7(-2) = 7.4
y = 7.4 + 1
7.4 + 1 = 8.4
y = 8.4
Answer - C) 8.4
Hope this Helps!!
5. since .6 is greater than 5, we round up.
