2016 is least common factor
Since it is a right angle you would subtract 57 from 90 because both angles added together are 90°. 90-57= 33°
2 quarters, 3 dimes, 4 pennies...total of 9 coins
probability of first drawing a dime = 3/9 reduces to 1/3
without replacement (means u have only 8 coins now)
probability of then drawing a quarter = 2/8 reduces to 1/4
probability of both : 1/3 * 1/4 = 1/12 or 8.3%
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12

You know three team members do the butterfly. One more team member does the breaststroke. Therefore, 4 members do the breaststroke, because 3 + 1 = 4. Three times more do the sidestroke than the breaststroke, so you have to multiply 4 by 3 and get 12. 12 members do the sidestroke. If you add the 3 memebers doing the butterfly, the 4 memebers doing the breaststroke, and the 12 members doing the sidestroke, you get 19. Since the other half of the team is doing the crawl, you have to multiply 19 by two to get the whole team. 19 times two is 38. There are 38 members on the swim team.
