Answer:
16 problems.
Step-by-step explanation:
100% divided by 20 questions.
100/20 is equal to 5, therefore each question is worth 5 points.
Grade of 80% divided by points per question.
80/5 is 16 so the student answered 16 questions correctly.
Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
He had 250 shirts to begin with.
Let x be the number of shirts he began with. He has 10%, or 0.10 of the shirts now he had then. This equals 25:
0.1x = 25
Divide both sides by 0.1:
0.1x/0.1 = 25/0.1
x = 250
Answer:
T=N*M and he needs to read 44 books.
Step-by-step explanation:
Note: Let T represent the total amount of books that Alan needs to read in 11 months.
If we plug in the information we have been given we will find the total:
T=N*M
T=4*11
T=44
Alan has to read 44 books within a 11 month period.

Functions are used to represent tables and equations
- The function that represents the number of imports is f(x) = 2x
- The function that represents the number of exports is f(x) = 2 + x
<h3>How to determine the import function</h3>
From the table, we can see that the values of the import is twice the number of months
This is represented as:
y = 2x
Rewrite as a function
f(x) = 2x
Hence, the function that represents the number of imports is f(x) = 2x
<h3>How to determine the export function</h3>
From the table, we can see that the values of the export is two more than the number of months
This is represented as:
y = 2 + x
Rewrite as a function
f(x) = 2 + x
Hence, the function that represents the number of exports is f(x) = 2 + x
