.10x + .05y = 4.50
x + y = 30
Is the formula
If your equation is 2v + 7 = 3,
Subtract 7 from both sides to get 2v = -4
Then divide 2 on both sides and get v = -4/2
Then simplify to get v = $-2
We know that 2 pints = 1 quart. So that means that 3 pints = 1 1/2 quarts
The correct answer would be she made 12 pints because 2 pints = 1 quart
Hope this helped!
You need to DIVIDE the 3/4 meter into 1/3 meter pieces, so....
(3/4)÷(1/3) = (3/4) *(3/1) = (9/4) = 2.25
She can cut 2 (1/3) meter pieces.
To find what is left subtract (2/3) from the original (3/4).
(3/4)-(2/3)= (1/12) meter
Angle C is π - (π/4) - (π/3) = 5π/12. The Law of Sines tells you
... a/sin(A) = c/sin(C)
... a = sin(A)·c/sin(C)
... a = sin(π/4)·10/sin(5π/12) ≈ 7.32
The length of the side opposite angle A is about 7.32.
