Step-by-step explanation:
The given formula is

It is given that a line segment has endpoints Q at –8 and S at 12. Point R partitions the directed line segment from Q to S in a 4:1 ratio. It means




Substitute these values in the given formula.

Therefore, the correct option is B.
(3x(a)-6x)- (6a-12) Multiply the outside with the inside
Answer:
12 °F
2°F per hour
Step-by-step explanation:
The difference can be found by substracting:
7°F-( -5 °F)
=12 °F
To find the average change in temperature per hour, divide by how many hours between 6 to midnight. Between 6 to midnight is 6 hours.
12°F / 6 hours
= 2°F/ hour
By making the surface rougher and to increase the force pushing the surfaces together.
Answer:
The least number of hours that she would have to work is 11.
Step-by-step explanation:
First, make the equation be "12.75x +100=235". Then, subtract 10 from both sides of the equation. You would get
"12.75x= 135". Then, divide both sides of the equation by 12. 75x, and the equation turns out to say, "x=10.59".
