-2w + 20 = -17 - 17 + 4w
Combine like terms on the right side of the equation.
-2w + 20 = -34 + 4w
Add 2w to both sides.
20 = -34 + 6w
Add 34 to both sides.
54 = 6w
Divide both sides by 6.
w = 9 is your answer.
1)1,2,3,4,5,6
2)1/2
3)1/2
4)1/3
5)5 OR LESS THAN FIVE =1/6
ONLY LESS THAN FIVE (EXCLUDING FIVE)=4/6=2/3
Answer:
uh, I think it's 4.13
Step-by-step explanation:
5*sin(65)=4.13 now this seems a bit off but this was the only one that actually worked
Answer:
b
Step-by-step explanation:
The median is the middle value of the data set in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.
Arrange the data in ascending order
48, 52, 54, 57, 57, 57, 61, 61, 65
↑
The median of the data set is 57 → b
