Let the constant of variation be c.
We are given that y varies inversely with 2.5x, this means that:
y = (c) / (2.5x)
This can be written as:
2.5xy = c
Now, we a re given that y = 5.6 at x = 30.
Substitute with these values in the equation to get the value of c as follows:
2.5xy = c
2.5(30)(5.6) = c
c = 420
Therefore, the equation that describes the relation is:
2.5xy = 420
2+6g=11-3g
-2+3g -2+3g
9g=9

Answer:
the cost of one hot chocolate is $2.
Step-by-step explanation:
Let x be the hot chocolate cost and y be the newspaper cost.
Given:
A newspaper and three hot chocolates cost $7
So, the equation is
--------(1)
Two newspapers and two hot chocolates cost $6
So, the second equation is.
---------(2)
Find one hot chocolate cost?
Solve equation 1 for y.
Put y value in equation 2
negative sign is cancelled both side.
Therefore, the cost of one hot chocolate is $2.
Tigers: 1 - 2/3 = .3333
Redbirds: 1 - 4/5 = .2
Bulldogs: 1 - 3/8 = .625
Titans: 1 - 1/2 = .5
The Redbirds likelyhood is lowest, therefore, they're least likely to play I'm the championship.
B is the correct answer.
