Answer:
-6
Step-by-step explanation:
2n can be the smallest integer, and 2n + 18 will be the largest integer.
The sum of this, divided by two, will result in the average/mean.
(2n + 2n + 18)/2 = 3
Multiply each side by 2:
(2n + 2n + 18)/2 ⋅ 2 = 3 ⋅ 2
2n + 2n + 18 = 6
Combine the like terms:
4n + 18 = 6
Subtract 18 from both sides:
4n + 18 - 18 = 6 - 18
4n = -12
Divide each side by 4:
4n/4 = -12/4
n = -3
Since we decided to go by 2n:
2n = 2(-3) = <u>-6</u>
Answer:
I think the answer would be 154 for the lowest and 169 for the highest.
Step-by-step explanation:
To find k, divide both sides by 1/4
K = 2/3 / 1/4
When dividing by a fraction flip the second fraction over then multiply:
K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3
K = 8/3 = 2 and 2/3
Answer:
a.
Step-by-step explanation:
there a hundread of times because 8 students 8 chairs they can do what set do want to do.
distance = speed * time
d = constant rate * 1/4 miles/hour
