Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

3 + 3(x + 2) = -24

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 3:                    3 + 3x + 6 = -24
  2. Combine like terms:       3x + 9 = -24
  3. Isolate <em>x</em> term:                 3x = -33
  4. Isolate <em>x</em>:                          x = -11

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    3 + 3(-11 + 2) = -24
  2. Add:                                     3 + 3(-9) = -24
  3. Multiply:                               3 - 27 = -24
  4. Subtract:                              -24 = -24

Here we see that -24 does indeed equal -24.

∴ x = -11 is the solution to the equation.

The diagram below shows the dimensions of a triangular park built in a new housing development. Two side lengths and one angle m
evablogger [386]
ANSWER

x = 50.5 \degree

EXPLANATION

We use the sine rule for solving triangles.

This is given by the formula,


\frac{ \sin(A) }{a}  =  \frac{ \sin(B) }{b}  = \frac{ \sin(C) }{c}


From the triangle,

\frac{ \sin(x) }{60}  =  \frac{ \sin(40) }{50}

We multiply both sides of the equation by 60 to get,

sin(x)  =  \frac{ 60\sin(40 \degree) }{50}


sin(x)  = 0.7713



We solve for x to obtain,

x = arcsin(0.7713)


x = 50.475

To the nearest tenth, we round to one decimal place to get,

x = 50.5 \degree

Solve the systems of equations y=2x and y=-x - 6
slava [35]

Answer:

y = -4

x = -2

Step-by-step explanation:

Hi there...

y = 2x

y = -x - 6

Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...

2x = -x - 6

add x on both sides...

3x = -6

divide by 3 on both sides...

x = -2

Now, plug in x for y. Here's what I mean...

y = 2x

y = 2 (-2)

y = -4

Hope this helps :)
