Since complementary angles add up to 90 degrees, we simple take
and simplify it to

Answer:
15 black marbles
Step-by-step explanation:
So its. A ratio (basically a fraction)
3/2
we add them up so we know how much marbles but not which kind
so we get 5
now we know for every 5 batches there is 3 black and 2 red
so we divide 25/5 to get 5
now we know there are 5, 5 batches of black ad red marbles.
now black is 3 of them so we multiply 5(3) which is 15
Now red is 2 of them so we multiply 5(2). Which is 10
now to check, if we add them up, they equal to 25 which is correct.
basically add the fraction, divide that by the original number, time the quotient by each number in the fraction.
Answer:
The lines are parallel
Step-by-step explanation:
Answer:
The answer is -5.
Step-by-step explanation:
Step 1: If you want to get the answer easier, you should use the number line way.
Step 2: If you don't know how to use a number line then go backwards from 18 until you have are done counting, for example;
17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, -4,<em><u> -5.</u></em>
Since -5 ( negative five ) is the 23 ( twenty-third ) number you counted back from, you are done counting and now you have gotten your answer of -5!
