Their were six slices of pie left, and then john took 1/5 of them. how much pie is left?
Answer:
OPTION A: 
, where 
.
Step-by-step explanation:
Given: 
Taking 
common outside in the denominator, we get:
will get cancelled on the numerator and denominator, we get:
we know that the denominator can not be zero.
That means, 1 + 8x 
0.
So, the answer is: 
, where 
.
It takes a while to see through this one.
I think that's because the triangle is in a weird position.
The arrows on the two across-lines tell us that those lines are parallel.
And THAT tells us that the two triangles are similar ... the whole big triangle,
and the smaller triangle on the bottom.
If two triangles are similar, then what ?
-- Their corresponding angles are equal. That doesn't help us in this problem.
-- Their corresponding sides are in the same ratio. That helps us a lot !
The left side of the big triangle = 5 + 8 = 13
The left side of the small triangle = 8
Now we know that corresponding sides of the two triangles
have the ratio of 13 to 8 .
The right side of the big triangle = 4 + x
The right side of the small triangle = x
The ratio has to be 13/8 , so ===> (4+x) / x = 13 / 8 .
That's the tough part. Now you take it and finish it off from here.

Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality r
For x=5.8, y=5.8
substitute
The linear equation is
therefore
The value of the constant of proportionality r is 1
