First find least common denominator to subtract.
9=(3)×3
15=(3)×5
3×3×5=45 is lcd
4/9=20/45
7/15=21/45
(20/45-21/45)=(20-21)/45=-1/45
-1/45÷13/10
multiply by reciprocal instead of dividing
-1/45×10/13=(1×10)/(45×13)
-10/585
I don't even know good sir, But it is most likely A
The formula for simple interest is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, i = ($315) (0.015) (3) = $14.18 (answer)
Answer:

Step-by-step explanation:
From the question we are told that:
Height of Eagle 
Angle of depression
Generally the trigonometry equation for diagonal X is mathematically given by





The solution of given system of linear equation is:
x=3 and y=10
Step-by-step explanation:
Given equations are:
-8x+5y=26 Eqn 1
9x-3y=-3 Eqn 2
Multiplying equation 1 by 9
-72x+45y=234 Eqn 3
Multiplying Equation 2 by 8
72x-24y=-24 Eqn 4
Adding Eqn 3 and 4

Dividing both sides by 21

Putting y=10 in equation 1

Subtracting 50 from both sides

Dividing both sides by -8

Hence the solution of given system of linear equation is:
x=3 and y=10
