27=a+11
To keep the equation balanced minus 11 from both sides to get 16=a
Answer:
x = 11, y=-½
Step-by-step explanation:
Simultaneous equations - subtract the first equation from the second.
x + 4y = 9
-(x - 2y = 12)
6y = -3
y = -½
Substitute y
x + 4(-½) = 9
x + -2 = 9
x = 11

Step-by-step explanation:
i just kinda figured it out
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.
