Answer:
The perimeter of the rectangle is 26 cm
Step-by-step explanation:
First find the area of the square by multiplying 6 by itself
A = 6 cm * 6 cm = 36 sq cm
Since the rectangle has the same area as the square, we can say that w * 9 = 36 sq cm
w * 9 = 36
Divide both sides by 9 to isolate the variable, w
w * 9 / 9 = 36 / 9
w = 4 cm
The width of the rectangle is 4 cm so now we just use that to find the perimeter of the rectangle
P = 2(9) + 2(4) = 26 cm
Add -11 and 15 to get 4
x^2 + 4
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:
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.
