M∠A = 42° [isosceles triangle]
m∠B = 180 - 42 - 42 = 96° [in a triangle, the three interior angles always add to 180°]
m∠C = 180 - 96 - (x+12)
m∠C = 84 - x - 12
m∠C = 72 - x2x+9 + 3x-1 + 72-x = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 100/4
x = 25m∠C = 72 - x = 72 - 25 =
47°

It is important to check all
the vital information’s given in the question.
<span>1 liter = 1000 ml
Then 6 liters = (1000 * 6) ml
= 6000 ml
Now
600 ml is the holding capacity of = 1 bottle
Then
6000 ml will be the holding capacity for =
(1/600) * 6000
= 10 bottles</span>
So a total of 10 bottles
having capacity of 600 ml can be filled with 6 liters. I hope the procedure is
easy enough for you to understand.
First you had to switch sides of equation.

Then you divide by two from both sides of equation form.

Simplify.

Next, subtract by i from both sides of equation form.

Finally, simplify by equation.

Final answer: 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

You can find your answer by just substituting -3 for x......
Answer: You can get 6 pounds of apples and approximately 19 apples.
Step-by-step explanation:
There are 16 ounces per pound so 6 pounds is 96 ounces
96/5 = 19.2
