Answer:
10(32 - n)
Step-by-step explanation:
This is a beginning algebra question. It is trying to find out if you know what a difference is.
A difference always means subtract in math. Always. There are no exceptions.
So the difference between 32 and n is 32 - n
This difference is multiplied by 10
10(32 - n)
Usually the number mentioned first is the number put to the left of the subtract sign.
If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.
79.90*0.8= 63.92
Answer
63.92
N(3)-8=16
add 8 to both sides
3n=24
Divide each side by three
n=8
Beth's speed was 60 mph.
<h3>
What is speed?</h3>
- The speed (commonly referred to as v) of an object in everyday use and kinematics is the magnitude of the change in its position over time or the magnitude of the change in its position per unit of time; it is thus a scalar quantity.
- The distance traveled by an object in a time interval is divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
- Velocity is not the same as speed.
To find what was Beth's speed:
Beth's data:
- time = 2 hrs; rate = r mph; distance = r×t = 2r miles
Tim's data:
- time = 1 hr; rate = r-6 mph; distance = r-6 miles
Equation:
- distance + distance = 174 miles
So,
- 2r + r - 6 = 174
- 3r - 6 = 174
- 3r = 180
- r = 60 mph (Beth's rate)
- r-6 = 54 mph (Tims's rate)
Therefore, Beth's speed was 60 mph.
