Answer:
B
Step-by-step explanation:
w=width
l=w+3
(w+4)=width+walkway(both sides)
(w+7)=length+walkway(both sides)
Using linear pairs,

By the exterior angle theorem,

Answer: The ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
Step-by-step explanation:
Given : Number of students who play the clarinet= 12
Number of students who play the viola=16
We know that ratio of A to B is represented by A:B.
Since, the number '12' is representing " students who play the clarinet" and number '16' is representing " students who play the viola"
So , the ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
Answer:
-1
Step-by-step explanation:
Choose two point on that line such as (1,1) and (2,0)
Then use slope formula y-y/x-x
1-0/1-2 = 1/-1 = -1
Y = -1/3x + 4 . 4 is the intercept -1/3x is the slope
