Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.

Answer:
The smaller angle is 18 degrees
The larger angle is 72 degrees
Step-by-step explanation:
x = smaller angle
y = larger angle
y = 4x ---> one angle is 4 times larger than other one.
y + x = 90 ----> the sum of complementary angles is 90 degrees
4x + x = 90 ----> plug in 4x for the larger angle (y) and then solve
5x = 90
x = 18 ----> the smaller angle is 18 degrees
y = 90 - 18
y = 72 ----> the larger angle is 72 degrees
There are 4 Queens, 4 Kings, and 4 Aces in a standard deck of cards.
Add these together, and there are 12 cards that you have a chance of choosing from.
The ratio of cards we want to get (queen, king ace) to number of cards is 12/52. This is the probability. We can simplify it further by dividing both sides by 4. We now have the fraction 3/13.
Therefore, the probability of drawing a queen, king, or ace is 3 in 13, or 23%.
hope this helped!
