Answer: D) 7</h3>
===================================================
Explanation:
a31 means "the value in the third row, first column". That value is 7
As another example, a22 = 3 since 3 is in the second row, second column.
Another example: a12 = -1 because we're in the first row and second column.
This is a 3x2 matrix due to it having 3 rows and 2 columns.
Ote: (21/n)n = 21)
Numbers 21/n and n
Question States***
(21/n) = 4n - 5
21 = 4n^2 - 5n
4n^2 - 5n - 21 = 0
(4n + 7) (n - 3) "Find the integers" n = -7/4 will Not work
n = 3 and the other number is 7 21%2F3
Answer:
-15 2/3.
Step-by-step explanation: First off, I performed the equation -4 5/1 - 6 4/6, yielding -15.6. I then translated that to a fraction. How to do that, you ask?
Example #1
Convert 0.32 to fraction:
0.32 = 32/100
Find the greatest common divisor (gcd) of the numerator and the denominator:
gcd(32,100) = 4
Reduce the fraction by dividing the numerator and the denominator with the gcd:
0.32 = (32/4) / (100/4) = 8/25
Example #2
Convert 2.56 to fraction:
2.56 = 2+56/100
Find the greatest common divisor (gcd) of the numerator and the denominator:
gcd(56,100) = 4
Reduce the fraction by dividing the numerator and the denominator with the gcd:
2+56/100 = 2 + (56/4) / (100/4) = 2+14/25
In your problem the final answer would result in -15 2/3. Hope this answered your question.
Answer: 18.75%
Step-by-step explanation:
Here is the complete question:
Last month, a cafe had 3200 customers. 600 of them ordered gluten-free meals. What percentage of the customers ordered gluten-free meals?
To find the percentage of the customers who ordered gluten-free meals, we will divide the number of people who ordered glutton free meal by the total number of customers and then multiply by 100. This will be:
= 600/3200 × 100
= 0.1875 × 100
= 18.75%
