Answer:
106 km / hour
Step-by-step explanation:
Givens
Total time: 6 hours
Total distance: 1356 km
First bus rate: r
Second bus rate: r - 14
Formula
d = r * t
Solution
r*6 + (r - 14)*6 = 1356 Remove the brackets
6*r + 6*r - 84 = 1356 Add like terms
12r - 84 = 1356 Add 84 to both sides
12r + 84 - 84 = 1356-84 Combine
12r = 1272 Divide by 12
r = 1272/12
r = 106 km/hr

Answer:
b. Continuous
Step-by-step explanation:
Continuous variable is a variable that can take on any value between its minimum value and its maximum value. A continuous variable is a type of quantitative variable used to describe data that is measurable while Discrete variables are countable in a finite amount of time. Now, justifying whether the gallons of gasoline pumped by a filling station during a day is continuous or discrete. The number of gallons of gasoline pumped by a filling during during a day is a continuous variable because it has a measurable volume which can take value from the minimum to maximum values of the total volume of gasoline the filling station have in the storage tank.
Greetings!
Solve for x.
Distribute the Parenthesis.
Combine Like Terms.
Add
1338 to both sides.
Subtract
668x from both sides.
![[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x](https://tex.z-dn.net/?f=%5B%28668x%2B900%29%2B1338%5D-668x%3D%5B%28672x-1338%29%2B1338%5D-668x)
Simplify.
Divide both sides b
y
4.
Simplify.
