5y - 3x = -47
y = -3x - 13
5(-3x - 13) - 3x = -47
-15x - 65 - 3x = -47
-15x - 3x - 65 = -47
-18x - 65 = -47
<u> + 65 + 65</u>
<u>-18x</u> = <u>18</u>
-18 -18
x = -1
y = -3(-1) - 13
y = 3 - 13
y = -10
(x, y) = (-1, -10)
If the angles of measures of angles X, Y, and Z are neither law of sine and cosine can be used to solve the triangle.
<h3>What is the law of
cosines and sines?</h3>
The law of cosines can be used to determine the measures of the triangle if the angles are known. The law is given by:
a² = b² + c² - 2bc*cosA
a,b,c are the sides and A, B, C are the angles.
The law of sines are used to determine the measures of the triangle if the angles are known. The law is given by:
a/sinA = b/sinB = c/sinC
If the angles of measures of angles X, Y, and Z are neither law of sine and cosine can be used to solve the triangle.

Answer:5728
Step-by-step explanation: 5728 stays the same but the second number had to be 3300 then you subtract.

- P=₹26,400
- R=15% p.a compounded yearly
- n=2 years and 4 months
Thus,the amount after 2years and 4months =₹34,914+₹1745.70=₹36,659.70
The answer is A. in the special store you spend $3 on gas + 1.30 the price of the beans times the pounds you want
