Answer:
yes its linear
Step-by-step explanation:
First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.
Rearrange equations


To cancel y, we must do equation 1 minus equation 2. Similarly:




So the x coordinate is 3.
The y coordinate can be found with substitution of x into one of the equations:

So where the two lines intersect is at the point (3, 7), which is the solution to the equations.
Answer:
they rest for 36 minutes
Step-by-step explanation:
27 minutes x
----------------- = ---------------
6 hrs 8 hrs
using cross products
27 * 8 = 6x
divide by 6
27*8/6 = x
36 minutes = x
36 or 6 * 6 because to find out how many possible contingency's you multiply the factors.
(2x+9)+(x)=180
3x+9=180
-9 -9
3x=171
÷3 ÷3
x=57
