Answer:

6 brownies and 2 cupcakes.

Step-by-step explanation:

Let the number of brownies be b and the number of cupckes be c.

We have the following system:

b = 3c

1.5b + 3c = 15

Substituting for  b in the second equation:

4.5c  + 3c = 15

7.5c = 15

c =  2.

Thus b = 3c = 6.

Cole buys a laptop for 335. He makes a $50 down payment and pays the rest in 6 equal payments,p. What equation represents the re
victus00 [196]

Answer:

The equation representing the relationships between the cost of laptop and Cole's payment is 50+6p=335.

Step-by-step explanation:

Given:

Cost of laptop = 335

Down payments = $50

Number of equal payments = 6p

We need to write the equation form the relationships between the cost of laptop and cole's payment.

Solution:

Now we can say that;

Cost of laptop is equal to sum of Down payments and Number of equal payments.

framing in equation form we get;

50+6p=335

Hence The equation representing the relationships between the cost of laptop and Cole's payment is 50+6p=335.

what is the probability of hitting each target if it is assumed that a player’s throw will always hit the board? hint: the proba
solong [7]
Because the actual dimensions of the board and the target are missing, let us supply the missing values. 

Let:

radius of board = 6 inches
radius of target = 2 inches

Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi

Probability of hitting the target = 4pi / 36pi = 1/9

Therefore, there is a 1/9 chance of hitting the target on the board.
