13.54 +2.063 +0.14 +52.1= 67.843
so the answer is D.
Use the substitution method:
2x - 6y = -12
x - 2y = -8
Then x = 2y - 8
Substitute in the first equation:
2(2y - 8) - 6y = -12
4y - 16 - 6y = -12
-2y = 4
y = -2
Now substitute y in one of the two equations given you prefer:
For example x-2*(-2) = -8
x + 4 = -8
x = -12
The solutions are x = -12 and y = -2
Answer:
The area of LQM is 
Step-by-step explanation:
Given
Area of PNQ = 8
Area of LPQ = 16
See attachment for triangles
The area of PNQ is calculated as:

Substitute 8 for Area


The area of LPQ is calculated as:

Substitute 16 for Area

From the attachment:

Make LP the subject

So:

We have:
and 
Equate both expressions:

Divide both sides by PQ

Multiply both sides by 2


Since PNQ is similar to LNM, the following equivalent ratios exist:

Substitute 



Area of LQM is:

This gives:


Recall that:

So:


2% of 6 million pennies are more than what they cost your answer would be $14,400,000,000 or $120,000
Complimentary means they add up to 90
x is the angle we're looking for
x + 89 = 90
Subtract 81
x = 90 - 89
x = 1
A is the correct answer.
