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!
Answer:
y = -1/4x + 4
Step-by-step explanation:
(8,2) and (-4, 5)
Slope = (5 - 2)/(-4 - 8)
= 3/-12 = -1/4
Point (8,2)
b = 2 - (- 1/4)(8)
b 2+ 2 = 4
Sally to get to the next town in 2/3 hour.
According to the statement
The distance covered by sally to get next town is 20 miles
Speed at which sally drive is 30 miles per hour
We know that the
TIME = DISTANCE / SPEED
Substitute the values in it and
TIME = 20 / 30
TIME = 2/3 hour
So, Sally to get to the next town in 2/3 hour.

Hey there! I'm happy to help!
If Mary's friend at 3/4 of blackberries, we will simply multiply the total number of blackberries by 3/4 to find how many blackberries Mary ate.
3/4×1 3/4= 1 5/16
Therefore, Mary's friend at 1 5/16 pounds of blackberries.
I hope that this helps! Have a wonderful day!
