<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>
Answer:
d = 0
Step-by-step explanation:
cancel equal terms on both sides of the equation
= 8d = 6d
move variable to the left and change its sign
8d - 6d = 0
2d = 0
divide both sides of the equation by 2
d = 0

The answer is Angle addition postulate
Answer:
C. 15.04°
Step-by-step explanation:
The best approach to this question is to use the Law of Sine: ![\frac{a}{sin(a)} =\frac{b}{sin(b)} =\frac{c}{sin(c)}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bsin%28a%29%7D%20%3D%5Cfrac%7Bb%7D%7Bsin%28b%29%7D%20%3D%5Cfrac%7Bc%7D%7Bsin%28c%29%7D)
We are given ∠48°, 63 on the longest side and 22 on the adjacent side (opposite of ∠B). This means we just have to set up our equation (remember to set calc to deg!!):
![\frac{63}{sin48} = \frac{22}{sinB}](https://tex.z-dn.net/?f=%5Cfrac%7B63%7D%7Bsin48%7D%20%3D%20%5Cfrac%7B22%7D%7BsinB%7D)
We solve by cross multiplying:
63sin(B) = 22sin(48°)
sin(B) = ![\frac{22sin48}{63}](https://tex.z-dn.net/?f=%5Cfrac%7B22sin48%7D%7B63%7D)
B = sin^-1 (
)
Plug the B equation into the calculator and your final answer should be 15.041°, which rounds to 15.04°.
