Answer:

Option B, x = 20

Step-by-step explanation:

Step 1: Make an equation

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

Step 2: Subtract 5 from both sides

65 - 5 = 3x + 5 - 5

60 = 3x

Step 3: Divide both sides by 3

60 / 3 = 3x / 3

20 = x

Answer: Option B, x = 20

The angle 65° is the same as the angle (3x + 5)° because their parallel.

We can write this as (3x + 5) = 65

Now, solve for x.

3x + 5 = 65

3x + 5 - 5 = 65 - 5

3x = 60

3x/3 = 60/3

x = 20 (Option B)

Best of Luck!

What is the exact value of the expression the square root of 20. + the square root of 24. - the square root 54.? simplify if pos

aksik [14]

$\sqrt{20} = \sqrt{4} \sqrt{5} = 2 \sqrt{5}$
$\sqrt{24} = \sqrt{4} \sqrt{6} = 2 \sqrt{6}$
$\sqrt{54} = \sqrt{9} \sqrt{6} = 3 \sqrt{6}$

Because you can only add and subtract radicals with the same radicand,
you get 2 $\sqrt{5} - \sqrt{6}$
that is the simplified answer but if you want it in decimals, 2.022 is what you get.

If g(x) = -2x + 9, what is the value of x when g(x) = 3?

MissTica

Answer:

x = 3

Step-by-step explanation:

1. Plug 3 into g(x)

3 = -2x + 9

2. Subtract 9 on both sides

-6 = -2x

3. Divide by -2 on both sides to get x by itself

x = 3

I hope this helped :)
