Answer:
-2×h
Step-by-step explanation:
because it drops-2 by hour so multiply-2 by the difference of hours

Answer:
<h2>8(7n - 2) - 6(7n + 1) = 14n - 22</h2>
Step-by-step explanation:
8(7n - 2) - 6(7n + 1)
use the distributive property: a(b + c) = ab + ac
= 8 · 7n + 8 · (-2) + (-6) · 7n + (-6) · 1
= 56n - 16 - 42n - 6
combine like terms
= (56n - 42n) + (-16 - 6)
= 14n - 22
Answer: x ≤ -5.5
reason:
first, multiply 4x and -2 by 1/2 and 6x and 9 by -2/3.
this makes the equation 2x-1-4x-6 ≤ 4
combine like terms to make it -2x-7 ≤ 4
add 7 to both sides to get -2x ≤ 11
divide both sides by -2 and get x ≤ -5.5
Answer:
The difference between the smallest and largest values in the tutored students’ data was 10 students.
Step-by-step explanation:
We are given that a tutor kept track of how many students she had helped every week for a year. The range of the number of tutored students was 10 students.
As we know that the range tells us the difference between the highest and the lowest value in our data set.
In this question, it is stated that a tutor helps a certain number of students every week in a year. So, there must be a week in which she helps the maximum number of students and there must be a week in which she helps the minimum number of students.
Range = Highest value - Lowest value
Hence, the difference between the smallest and largest values in the tutored students’ data was 10 students. This is the best interpretation of this value.
