9514 1404 393

Step-by-step explanation:

In order to determine the value of x, the measure of angle BCA must be known. If we assume the figure is a kite, then ...

  ∠CDB = ∠CBD = 61°

  ∠CBD +∠BCA = 90°

So, the measure of angle BCA is ...

  ∠BCA = 90° -∠CBD = 90° -61°

  ∠BCA = 29°

__

Now we can find x from ...

  29° = (-6 +x)°

  29 +6 = x = 35

8y^50

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
