Let one acute angle be X and one be Y
X+Y=90 -------Eq.1
2X+12=Y
2X-Y=-12------Eq.2
solving eq 1&2 we get,
3x=78
∴X=26
substituting value X in equation.1
X+Y=90
Y=90-26
∴Y=64
⇒answer:- X=26°
Y=64°

Answer:
Assuming you mean until the lunch money balance runs out,
$2.20x = $23
Step-by-step explanation:
You spend $2.20 every day. If you are trying to find how many days until the lunch balance runs out, you need to put in X as your variable.
The last step is to set it equal to $23 dollars to be able to factor out the answer.
Hope this Helped!
Answer:
c
Step-by-step explanation:
because it is a outlier we can assume these 2 things:
it influences the mean and median, with the mean being effected more
because we know this, we can now solve the problem
both the median and mean decreased, but the mean decreased more than the median
Answer:
Linear approximation is given by: 
Step-by-step explanation:
We are given the following information in the question:
Number of citations: 5 7.5 10 15 20
Outputs Residuals: 3 6 10 5 6
We have to find the linear approximation of the data that passes through the points (5, 3) and (20, 6).
Linear approximation is given by:
The equation of line is given by:

where,
is the point through which the line passes.
The equation of line is:

The above equation is the required linear approximation.
