Just do 8 1/3 divided by 5/9 or
25/3 / 5/9
25/3 * 9/5 = 5/1 * 3/1 = 15
So 15 tacos
* = times
/ = divided by
Answer: -4x^2 + 8xy - 20y^2 + 12
Step-by-step explanation:
-4 (x2 - 2xy + 5y2 - 3)
-4(x^2) = -4x^2
-4(-2xy) = 8xy
-4(5y^2) = -20y^2
-4(-3) = 12
Answer: 0 = 3
Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.
- 7 - 7
--------------------------
3x - 3x = 3
0 = 3
Answer:
types of reading instruction - independent variable
reading comprehension of students - dependent variable
Explanation:
When it comes to the "experimentation" of a study, there are factors or variables that are being considered. These are <em>"independent variable</em>" and <em>"dependent variable."</em>
Independent variable refers to the variable that is being controlled. This affects the dependent variable. The influence of the independent variable on the dependent variable is <u>very important.</u>
So, in the situation above, the independent variable is the "types of reading instruction for a school year" while the dependent variable is the "reading comprehension" of the students.
<em>This means that the reading comprehension of the students will largely depend on the types of reading material.</em>
Thus, this explains the answer.
Answer:
C. 
Step-by-step explanation:
Given:
Cost Price for producing 'd' dog lashes = 
Revenue Generated from selling 'd' dog lashes = 
We need to find the profit earned from producing and selling 'd' dog lashes.
Solution:
Now we know that;
profit earned from producing and selling 'd' dog lashes can be calculated by Subtracting Cost Price for producing 'd' dog lashes from Revenue Generated from selling 'd' dog lashes.
framing in equation form we get;
Profit earned = 
Now Applying Distributive property we get;
Profit earned = 
Now Combining like terms we get;
Profit earned = 
Profit earned =
Hence Profit earned from producing and selling 'd' dog lashes is .
