-7w + 2(w + 8) = -24

First, expand your equation.
-7w + 2w + 16 = -24
Second, add '-7w + 2w' to get '5w'.
-5w + 16 = -24
Third, take away '16' from both sides.
-5w = -24 - 16
Fourth, subtract '-24 - 16' to get '-40'.
-5w = -40
Fifth, divide both sides by '-5' and change it into a positive.
w =  \frac{40}{5}
Sixth, how many times does 5 go into 40? 40 ÷ 5 = 8.
w = 8

Answer: w = 8

Graph the system of equations on graph paper. {8x+6y=482x−3y=−6 Which statements are true about the solution to the system of eq
GuDViN [60]

Answer:

The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I

Step-by-step explanation:

To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.

8x + 6y = 48

4x - 6y = -12

-------------------

12x = 36

x = 3

Next, find the y value by plugging in the x value to either equation and solving.

2x - 3y = -6

2(3) - 3y = -6

6 - 3y = -6

-3y = -12

y = 4

Find the angle of XZY
qaws [65]

Answer:

<h2>23.6°</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • trigonometry i.g sin(x)=opp/hypo
  • PEMDAS
<h3>given:</h3>
  1. opp:6
  2. hypo:15
<h3>to find:</h3>
  • xyz angle

<h3>let's solve:</h3>

let \: xyz \: angle \: be \:  \alpha

according \: to \: the \: question

\sin( \alpha )  =  \frac{xy}{zy}

\sin( \alpha )  =  \frac{6}{15}

\alpha  = asin( \frac{6}{15} )

\alpha  =  {23.6}^{o}

therefore
