Abag 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 coins as $1 bills, how many 50 cents coins are in the bag?

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:

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

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

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

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

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
