TOPIC: similtaneous linear equations

p1 + 2q = 3,
p - 2q = 3

p = 3 ; q = 0

Step-by-step explanation:

In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that

& also . So, we can also equate them as :-

(∵ Both the eqn. have 3 in their right hand side product )

Solving the eqn. gives,

Putting the value of q in any one of the linear eqn gives ,

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
