Mathematics

Answer:

Option B. 7.6

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 y/x=k or y=kx

where

k is the constant of proportionality

The slope of the linear equation is the same that the constant of proportionality

In this problem we have

y=7.6x

so

the slope is m=7.6

therefore

The constant of proportionality k is k=7.6

A bag contains only 50 cent coins and $1 bills. The total amount of money in the bag is $36. If there are twice as many 50 cents
vlabodo [156]

Answer:

The total number of 50 cent coins in the bag = 36.

Step-by-step explanation:

Let x be the number of 50 cents coins and y be the number of $1 bills.

We have been given that the total amount of money in the bag is $36. We can represent this information as:

0.5x+y=36...(1)

We are also told that there are twice as many 50 cents coins as $1 bills. We can represent this information as:

x=2y...(2)

Now we will use substitution method to solve our given system of equations. Upon substituting equation (2) in equation (1) we will get,

0.5(2y)+y=36

y+y=36

2y=36

\frac{2y}{2}=\frac{36}{2}

y=18

Now let us substitute y=18 in equation (2) to find our x.

x=2*18

x=36

Therefore, there are 36 fifty cent coins in the bag.
