Answer:
40$,160$ & 60
Step-by-step explanation:
First,find the equation using y-y1/ y1-y2=x-x1=x1-x2
y-0/0-20=x-0/0-3
y=20x/3
Now put the values of x& y in the equation, for the 1st one,
y=20×6/3
=40
2nd one.y=20×24/3
=160
3rd one,
400=20x/3
X=400×3/20
=60
Answer:
The second part of 72 is 
Step-by-step explanation:
The whole part is given as = 72
One part of it = 1/3
Let the other part of it = k
Now,according to the question:
First Part + Second Part = 72
or, 
⇒
or, 
or, k = 215/3
Hence, the second part of 72 is
Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
300-20x less than our equal to 100
