when solving an equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10​
alekssr [168]

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.

Two angles are complementary. If one angle is 4 times larger than other one then what is the measure of the smaller
arlik [135]

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

When one card is drawn from a well shuffled deck of 52 cards what is the probability that it will be a queen king or ace
andreev551 [17]

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!
