Let's solve your equation step-by-step.
6+2s−8s=18
Step 1: Simplify both sides of the equation.
6+2s−8s=18
6+2s+−8s=18
(2s+−8s)+(6)=18(Combine Like Terms)
−6s+6=18
−6s+6=18
Step 2: Subtract 6 from both sides.
−6s+6−6=18−6
−6s=12
Step 3: Divide both sides by -6.
−6s/−6
=12/−6
s=−2

Answer:
f(x) = 70 + 2x
Step-by-step explanation:
In this problem, we first need to consider how much we get per day.
$70 is our constant.
$2 will be dependent on the number of books sold.
Here 'x' will represent the number of books sold.
f(x) = 70 + 2x
Now let's try it out.
Let's say we sold 0 books
f(0) = 70 + 2(0) = 70
This shows us that we only get our constant pay.
Now let's try for 1 or more books.
f(1) = 70 + 2(1) = 72
f(2) = 70 + 2(2) = 74
So the recursive formula f(x) = 70 + 2x is a good formula to model the situation.
Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km

Answer:
220
Step-by-step explanation:
When the relationship is proportional, there are several ways you can find missing values. One of them is to recognize the distance for 4 hours will be double the distance for 2 hours.
2 hours : 110 miles
4 hours : 2×110 miles = 220 miles
