Answer:
The score of the dropped grade is 6
Step-by-step explanation:
To find the average of a set of numbers you need to add all the numbers and divide by how many numbers there are. The problem wants you to solve it in reverse. Let put this into an algebraic equation with a, b, c, d, and e being the variables of the test scores
(a+b+c+d+e)/5=10
Then we can multiply both sides by 5 and get
a+b+c+d+e=50
Lets assume that c is the lowest test score. To calculate the average of that we get
a+b+d+e/4=11
Doing the same thing, we know that a+b+d+e=44
Now compare the two:
a+b+c+d+e=50
a+b+d+e=44
We can now know that c=50-44=6
So, 6 is the score of the dropped quiz. Hope that helped!
If you meant “g(f) 3 evaluating it will give you 3gf by just moving the 3. Hope this helps.
Answer:
No
Step-by-step explanation:
For a point to be a solution of a system of equations, it has to work for both equations in said system. For this particular point, it doesn't fit into both.
12=5(2)+2
12=10+2
12=12
4(2)-12=0
8-12=0
-4=0
The second equation doesn't work out.
Answer:
(a) 680 km
(b) 680000 m
Step-by-step explanation:
(a) Distance run by hunter every day = 6.8 km
Total number of days under consideration = 100
So the total distance covered by the hunter = ![\[6.8 * 100\] ](https://tex.z-dn.net/?f=%5C%5B6.8%20%2A%20100%5C%5D%0A)
= 680 km
The hunter ran 680 km in the last 100 days.
(b) Converting this value to meters:
1 km = 1000 m
=> 680 km = 680 * 1000 m
= 680000 m
The equivalent distance run by the hunter when converted to meters is 680000 meters.
